How to establish a VPN connection without using my DNS - proxy

Is there any way for me to connect to a VPN without having it use my DNS? My internet provider where im connected can only use the DNS to connect to a separate server, which then connects to the internet as the router only interacts with that server, so if I change my DNS, my connection instantly stops working.
Is there any service that connects to a server without DNS as a VPN, or even some way to set up a proxy to go to another server after it interacts with my DNS?
Tried Changing DNS, no connection using cloudflare or google DNS servers (1.1.1.1, 8.8.8.8), Hotspot Shield VPN wouldn't connect, VPN from my home network wouldn't connect.

So, your ISP allows DNS traffic only to its server. And you want to by-pass this limitation.
Solution 1: SSH Proxy
ssh -D 5000 user#host
Now, you can set your applications to use proxy on socks5://localhost:5000
You must set "Proxy DNS on socks5"
This proxy goes throught the SSH server
Of course you need SSH server somewhere to connect to.
Solution 2: DNS over HTTPS
https://en.wikipedia.org/wiki/DNS_over_HTTPS
https://manpages.ubuntu.com/manpages/bionic/man1/dnss.1.html
It should work because your DNS packages go as HTTPS packages.
Solution 3: VPN or other services like nordvpn
It should work also since packages go encrypted to the VPN.
Actually, VPN should work without your ISP DNS as long as you connect to the VPN IP address instead the hostname.
Finally
Solution 2 seems to be the only one you are able to perform without external services.

Effectively bypass chatgpt cloudflare by using different proxy package or different cloud service provider in restricted countries

I have an account in chatgpt but as I located in the restricted country, I tried to use AWS proxy (US server) to login chatgpt. Few weeks ago it worked but now I get an error message access denied error code 1020. I used tinyproxy in stealth mode at first but since I was unable to pass through the cloudflare, I guessed probably the proxy was not good enough to disguise itself as a proxy, so I tried squid vpn in stealth mode and algo vpn, but all did not work(Tried other AWS countries server as well other than US). Until now, I figure out chatgpt might probably just banned all connection from amazon or perhaps my proxy is just not smart enough to pass through cloudflare? What are more options? Any recommended free vpn proxy that I could installed into my AWS EC2 or perhaps I should try other less known cloud services instead? e.g. (other non-restricted country's local cloud services) Besides, I have consider using other free proxy from the internet but as I need to login my gmail, is it danger to do so but since its https so my username and password should be encrypted?
I have the same problem, simple ssh tunneling works you can use a jump server to bypass your country first and than use different server to use as proxy because some of your vps servers get banned with IP, so you may have to use another vpn with different proxy
ssh -D "port to make SOCKS 5 Connection like" <10808> -J <"user">#<"jump server IP"> <"user">#<"final server IP">
than you can use "foxyproxy" extention to build SOCKS5 proxy that uses specified port in this example 10808 to route your browser terrafic through tunnel in port 10808 to final server
or you can use something like sshuttle, but i was fine with this simple tunneling method in GFW

SSH connect from local windows VM to Azure windows VM

I want to have a SSH connection from my local windows machine or VM on my computer to Azure windows server VM. I tried Cygwin and Putty but both of them gave timeout connection. I used public ip address and opened port 22 on Azure VM.
I will appreciate if some one can give me any hints or links.
There are multiple firewalls that can be the reason here. Fist you must have a rule on the server to allow incoming SSH requests (port 22). Then you need to configure the NSG(Network security group) to allow incoming on port 22. If it still doesn't work, you need to verify that you are allowed to do an outgoing SSH request from your computer.
Thanks for suggestions, I found the problem which was the host machine IP address(ipconfig) (where is a local VM inside domain) was different from the IP address that communicate outside the domain to internet. I was set in NSG of Azure VM to only accept this IP and because of that it gave time-out error. After changing the IP it works.

Connect to WebMin from external network

I have set up a new NAS using Open Media Vault. I have installed the WebMin extension to get on to the web gui for configuration. My problem is that I have to be on the same network as my NAS. How can I connect to my NAS from a different network than it is connected to? On the network that it is connected to its IP is 192.168.0.99:1000 for the WebMin gui. How can I access this from a different network?
Setup a VPN to connect to the network that your NAS is on. Once the VPN is connected you can connect to the NAS as if you were on the local network.
You could also possibly setup firewall and/or port forwarding rules depending on how your network is setup but please consider the security issues when doing so.
You could alternatively also try to open the NAS and give it a public IP address and a DNS. This will allow you to setup SSH and FTP as it was any other server.
To SSH remotely over the internet, you need either a permanent IP address or a domain name that is updated to point to the IP address when it changes. The latter requires a dynamic domain name service. A good free one is DuckDNS (duckdns.org). First, use one of the sign-in options such as Google. In the domain line enter your preferred subdomain name.
There is a great guide on how you can do this here: https://forums.freenas.org/index.php?threads/how-to-how-to-access-your-freenas-server-remotely-and-securely.27376/

Browser Proxy Connection Over VPN

I have a VPN (pptpd) server configured and a client connected. In the same machine of VPN server, I have a proxy server (port 3128)(squid) running with authentication enabled. When I use the proxy in my firefox browser it works fine. However, when I conect my notebook to my VPN server I can't navigate using firefox + proxy. Just to remember Proxy server and VPN server running in same machine (a VPS). I'm using UFW firewall.
Is there some tips in configuration files (pptpd or squid) to get this problem fixed?
Best Regards!
use squid's access.log to make sure: squid doesn't receive requests from your notebook; check the routing availability between internal IP network of VPN server and proxy address, it must be accessible (pingable). you may use port address translation (PAT) as a simple fix.

Do we have to buy a domain to serve Bugzilla?

I tried putting my IP from whatismyip.com in the urlbase of Bugzilla but it did not work. I wasn't able to create a new account for my team mate, and he wasnt able to access the server by typing the my ip address in his browse. And surely, when I connect again, my IP address will change. Do we have to buy a www address to host Bugzilla?
You can setup a dynamic dns service, for example via http://www.dyndns.com or http://www.no-ip.com or http://freedns.afraid.org to solve the changing ip problem without buying a domain (or buying a domain as well, but it's not a requirement).
But the real problem is that your team mate cannot access the server via the current IP address which points to either a misconfiguration of the webserver (listening only on localhost?), to a firewall in between, or most likely, that port forwarding isn't set up in your router for requests coming to your external IP address to be forwarded to the machine where you have Bugzilla set up. Additionally, you must set the urlbase to your local IP address, not to the external IP address, as blak3r says.
Check http://www.portforward.com for instructions on how to do port forwarding. But don't forget that everything mentioned has to be working:
Web server listening to outside requests: This can be tested from the same internal network via the local network IP address (what you see typing in a command line console ipconfig in Windows and ifconfig in Linux). If you can connect from a different machine on the same network via the local IP address, this is solved.
Firewalls (in router and the webserver machine) accepting connections to the web server port: For firewalls in the web server, the same test as above covers it.
Port forwarding so the router forwards the requests received on the web server port to the web server machine: This gets tested in the same way as firewalls in the router, that is, you must have your friend (or yourself from the house of your friend) try to connect to the dyn dns name set up or to the external IP as reported by whatsmyip.org.
This is all assuming your test mate is not on your same network, if he is, just using the local IP address (shown via ipconfig or ifconfig) instead of the external IP address and making sure the first step is covered (web server listening to outside requests) should be enough and nothing else is needed!
You most likely do not have your port 80 forwarded to your machine which is the reason he cannot connect when using the IP that was returned from whatismyip.com.
Assuming you're on a windows box... do
Start->Run->cmd then type
ipconfig
If your address starts with 192...* or 10...* this is your Local Area Network (LAN) IP. If this is the case, then your isp provided you with a router. Look for a setting called port forwarding or "application setting" which allows you to forward all incoming traffic on your router to a particular IP address. Go into your router's configuration settings and make sure port 80 (and maybe 443 if you're using ssl are forwarded to your local ip).
The other problem you mentioned is you do not have a static IP. This is a common problem and no you do not need to buy an address. There are several sites which can provide you a free dynamic dns host. Try no-ip.org.
