Want to setup a Azure Network adapter on a Windows Server 2019 DE machine. However, it does not matter what I try, the same error occurs:
Error: Virtual Network Gateway submission
Message Failed to submitted the update request of Microsoft Azure
Virtual Network Gateway WAC-Created-vpngw-99, Detail error message
from Azure: The BgpPeeringAddress for the virtual network gateway
/subscriptions/xxxxx/resourceGroups/Nett/providers/Microsoft.Network/virtualNetworkGateways/VPN-Gateway
cannot be modified
Also tried to Configure BGP ASN on the Azure gateway adapter, with an ASN number in the private range. No luck.
Any help will be grately appriciated.
As far as I know, the BgpPeeringAddress for the virtual network gateway is a specific IP address, which is the second last address from the GatewaySubnet range. The official DOC states this:
The Azure VPN gateway will allocate a single IP address from the
GatewaySubnet range defined for the virtual network. By default, it is
the second last address of the range. For example, if your
GatewaySubnet is 10.12.255.0/27, ranging from 10.12.255.0 to
10.12.255.31, the BGP Peer IP address on the Azure VPN gateway will be 10.12.255.30. You can find this information when you list the Azure VPN gateway information.
I can reproduce your issue, when I change the BgpPeeringAddress to an invalid IP address 172.24.1.250. A valid IP address should be IP address 172.24.1.254 in my GatewaySubnet range 172.24.1.0/24
I check this via Azure Resource Explorer. You can get more details from this blog.

I am trying to set up OpenVPN so that I can access machines inside an Azure subnet from my pc which is outside Azure.
I have successfully installed OpenVPN on both server (Windows Server 2019) and pc (Windows 10) using the instructions here: https://community.openvpn.net/openvpn/wiki/Easy_Windows_Guide?__cf_chl_jschl_tk__=pmd_889e3e419b8b865ffd4da6e493bef6df0782273e-1629275604-0-gqNtZGzNAfijcnBszQgi, and I can successfully connect from client to server, however, I cannot connect to any other machine on the Azure subnet upon which the server is sitting.
The server and the other machines I want to connect to are on a 10.0.0.0 subnet, and the VPN is coming up on the 10.8.0.0 network as I would expect from the examples.
I have enabled IP routing on the server as recommended in the OpenVPN FAQ but this has not fixed the issue.
I have also added a 'push "route 10.0.0.0 255.255.255.0"' line to the server config, and I can see from the client log (and the client routing table) that this has been executed, but I am still unable to connect to other machines in the subnet.
I was looking into using Tap instead of Tun, but when I dug into at what was actually being used, it looks as if as if both ends are using the Tap adaptor anyway, even though I have specified 'dev tun' in both the client and the server configs.
I have had bit of a trawl but can't find anything about the Tap adaptor when the Tun adaptor has been configured, so that is a bit of a mystery.
The only other thing that I have read is that it might be necessary to set up a route back to the OpenVPN subnet on the gateway server for 10.0.0.0, but that's not a server I control as it's part of the Azure infrastructure.
What do I have to do to get access to other machines on the 10.0.0.0 subnet? And why is the Tap adaptor being selected despite the config specifying the Tun adaptor ?
I made a number of other changes before I finally got it sorted out - I do not know if they were all necessary but in addition to the above:
I changed 'dev tun' to 'dev tap' in the server and client configs.
I followed the instructions here NAT-hack to add NAT to the server.
And finally, I added 'route 10.0.0.0 255.255.255.0 10.8.0.1' to the
server config file.
I have storage account that contains one container, When I am generating SAS token from Portal without IP restriction it is working fine but when I am generating SAS token from portal with IP restriction, then it is not working. I am providing the Vnet IP range in the IP range column. But when I am trying to access through Azure Explorer which is installed in one of the VM inside the Vnet address space, it is giving error "This request is not authorized to perform this operation using this source IP".
Vnet Ip range -192.168.0.0/24 and VM private IP is 192.168.0.68.
I do not know from where this 100.74.202.44 source IP is coming. VM private is 192.168.0.68 and its public IP is also different i.e 52.34.X.X.
Let me know what I am doing wrong here or this is Bug?
VM private is 192.168.0.68 and its public IP is also different i.e 52.34.X.X. Let me know what I am doing wrong here or this is Bug?
Base on my knowledge, it is the internal IP that VM get from the Azure DataCenter by DHCP. On the Azure classic portal we can get the internal ip from the Classic VM Dashboard as following:
But in the Azure new portal, I can't find it out.
When try to visit the Azure storage from the Azure VM then it seems that via Azure internal Ip 100.x.x.x.
So please have a try to add this IP for restriction to generate SAS token, then it will work.
I'm unable to join an EC2 instance to my Directory Services Simple AD in Amazon Web Services manually, per Amazon's documentation.
I have a Security Group attached to my instance which allows HTTP and RDP only from my IP address.
I'm entering the FQDN foo.bar.com.
I've verified that the Simple AD and the EC2 instance are in the same (public, for the moment) subnet.
DNS appears to be working (because tracert to my IP gives my company's domain name).
I cannot tracert to the Simple AD's IP address (it doesn't even hit the first hop)
I cannot tracert to anything on the Internets (same as above).
arp -a shows the IP of the Simple AD, so it appears my instance has received traffic from the Simple AD.
This is the error message I'm receiving:
The following error occurred when DNS was queried for the service
location (SRV) resource record used to locate an Active Directory
Domain Controller (AD DC) for domain "aws.bar.com":
The error was: "This operation returned because the timeout period
expired." (error code 0x000005B4 ERROR_TIMEOUT)
The query was for the SRV record for _ldap._tcp.dc._msdcs.aws.bar.com
The DNS servers used by this computer for name resolution are not
responding. This computer is configured to use DNS servers with the
following IP addresses:
10.0.1.34
Verify that this computer is connected to the network, that these are
the correct DNS server IP addresses, and that at least one of the DNS
servers is running.
The problem is the Security Group rules as currently constructed are blocking the AD traffic. Here's the key concepts:
Security Groups are whitelists, so any traffic that's not explicitly allowed is disallowed.
Security Groups are attached to each EC2 instance. Think of Security Group membership like having a copy of an identical firewall in front of each node in the group. (In contrast, Network ACLs are attached to subnets. With a Network ACL you would not have to specify allowing traffic within the subnet because traffic within the subnet does not cross the Network ACL.)
Add a rule to your Security Group which allows all traffic to flow within the subnet's CIDR block and that will fix the problem.
The question marked as the answer is incorrect.
Both of my AWS EC2 instances are in same VPC, same subnet, with same security group.
I have the same issue. Here are my inbound rules on my security group:
Here is the outbound rules:
I can also ping from the between the dc and the other host, bi-directional with replies on both side.
I also have the DC IP address set as the primary and only DNS server on the other EC2 instance.
AWS has some weird sorcery preventing a secondary EC2 instance from joining the EC2 domain controller, unless using their managed AD services which I am NOT using.
The other EC2 instance has the DC IP address set as primary DNS. And bundled with the fact I can ping each host from each other, I should have ZERO problems joining to domain.
I had a very similar problem, where at first LDAP over UDP (and before that, DNS) was failing to connect, even though the port tests were fine, resulting in the same kind of error (in network traces, communication between standalone server EC2 instance and the DC instance stopped at "CLDAP 201 searchRequest(4) "" baseObject", with nothing being returned). Did all sorts of building and rebuilding, only to find out that I was inadvertently blocking UDP traffic, which AWS needs for both LDAP and DNS. I had allowed TCP only, and the "All Open" test SG I was using was also TCP only.
D'oh!!!
I am trying to connect the Microsoft Azure network to a 3rd party provider.
We need to modify our access control lists to a specific host/ip.
How can we configure Windows Azure Virtual Networks to a limited to a network range i.e. one IP address , 2 IP addresses max ?
Only Virtual Machine endpoints provide the ability to set network Access Control Lists (ACLs) as documented here: https://azure.microsoft.com/en-us/documentation/articles/virtual-networks-acl/
There is a proposed idea to implement similar functionality on Virtual Network subnets which has reached the "planned" phase. I suggest you have a look at this thread: http://feedback.azure.com/forums/217313-networking-dns-traffic-manager-vpn-vnet/suggestions/3139676-add-the-ability-to-set-firewall-rules-at-the-subne
We are a small, 300-seat organization with a mixed BYOD and Active Directory environment (Windows Server 2012 Standard, Windows 7 Enterprise) and we are having a very strange problem involving very specific-scope failures to resolve our organization's domain name on our domain-joined, company-controlled machines. For the purpose of this discussion, I'll use company.com instead of our domain name.
Background:
Active Directory Domain Controller is located at 172.16.1.3
The AD/DC machine is also running DHCP, DNS, and HTTP (IIS)
Our organizations websites at company.com and subdomain.company.com are hosted by IIS on the AD/DC machine
We have a split-DNS scenario in which the AD/DC server is used for internal DNS resolution but a different, off-site server provides DNS resolution for public queries
The IP address corresponding to company.com and subdomain.company.com is the public IP address used by a firewall at the edge of our network (both on the AD/DC DNS server and the off-site DNS server)
The firewall is correctly configured for NAT to pass HTTP and HTTPS requests it receives on its public IP address to the internal IP of the AD/DC server and reflects
Scenario 1:
A user on a domain-joined Windows 7 Enterprise machine is connected directly to our local network with local address 172.16.6.100 /16, issued by the DHCP server.
The DNS server entry is provided by DHCP (172.16.1.3)
This user is able to access the websites hosted at company.com and subdomain.company.com
Edit: nslookup has been run in this scenario and correctly returns the proper DNS record from the internal DNS server (172.16.1.3)
Scenario 2:
The same user on the same domain-joined Windows 7 Enterprise machine goes home and connects to the Internet using their residential ISP
The IP and DNS server entries for the client machine are provided by DHCP
This user can access any internet resources, such as google.com
This user cannot access the website at company.com or subdomain.company.com (a "host not resolved" error is returned)
When this user runs nslookup on company.com they DO receive the correct public IP address provided by DNS
HTTP/HTTPS requests to the IP address succeed and a webpage is returned properly by the server
This issue prevails across all web browsers
Using tracert company.com returns "unable to resolve target system name"
Using ping company.com returns "could not find host company.com"
When running Wireshark on the client before/during a failed request, no packets are sent by the client machine (either for DNS resolution or for an initial HTTP/ping/tracert request)
Restarting the DNS Client service does not resolve the problem
Stopping the DNS Client service does not resolve the problem
Using ipconfig /flushdns does not resolve this issue
Using route /f does not resolve this issue
Resetting the network connections using netsh int ip reset does not resolve this issue
Edit: nslookup has been run in this scenario and correctly returns the proper DNS record from the DNS server specified by the DHCP settings of the network used by the user
Scenario 3:
This same user on a personal (not domain-joined) Windows 7 Professional computer is able to access the websites at company.com and subdomain.company.com when connected to our local network
Edit: nslookup has been run in this scenario and correctly returns the proper DNS record from the internal DNS server (172.16.1.3)
Scenario 4:
This same user on a personal (not domain-joined) Windows 7 Professional computer is able to access the websites at company.com and subdomain.company.com when connected their home network
Edit: nslookup has been run in this scenario and correctly returns the proper DNS record from the DNS server specified by the DHCP settings of the network used by the user
Final Notes:
This issue seems to be generalized to affect all company-owned computers. We are using a common system image for all company-owned computers, which was just loaded in August. I have been scouring the internet in search of possible solutions and have come up empty handed so far -- I really appreciate any suggestions or advice you may have.
This is quite an interesting scenario. Looking at your scenario 3, user with personal computer can access the services but why is the DNS entry coming from your corporate IP and not users home DNS. Is the machine on company network?
Verify this:
When user tries to access service from home on company computer, is the IP details from home internet router or company network via VPN?
