I have a dlink router..Dlink DIR 600M...I am trying to port forward 1337 and 1334 through my router and opened listener but after enable i checked canyouseeme.org but theres no port opened..i have a cable net connection...my wan ip and public ip is different.
If your WAN IP address and your Public IP addresses are different, you will need to be sure that you first port forward from the public-facing router to your D-Link router. If you do not have access to your public facing router (as is the case with my current network setup), then this port forwarding is not possible.
I have a DIR-651, and there are check boxes next to all the Port Forwarding rules. Make sure those are checked. I've wasted hours of troubleshooting because one of the boxes wasn't checked and saved.
Finally, make sure that you have a server running on the correct IP address and port that you specified on your router. Also, make sure that your firewall is disabled on those ports. If your server isn't configured to respond on those ports, then canyouseeme.org will not respond that those ports are open.

So this is a very basic question. I built a small spring boot web app. It runs on port 8089.
I want to take the website live. So i bought a domain that points to the IPv4 address of my server. As i can't specify a port on my dns server, traffic won't reach my application.
How do i get my website to be displayed?
Thanks a ton
Execute this command. I am assuming that your server is linux server.
sudo /sbin/iptables -t nat -I PREROUTING -p tcp --dport 80 -j REDIRECT --to-port 8089
This command is to route all the traffic you receive on port 80 to port 8089

Using static routes is it possible to access a host with an IP address of 1.2.3.4 on port 4000 that is connect to rtrnode on a wlan network that has a public ip address of x.x.x.14 from a remote host (h1)?
h1 -------router-------INTERNET-------(public IP(x.x.14)) = rtrnode(1.2.3.3)---------destination(1.2.3.4)
NO: Unless:You tunnel. This way the foreign LAN is a hop from the LAN you are on according to the routers on both ends that handle the packetizing and perform the VPN. It is easiest to set this up using firewalls like : PFSense or the likes. This link explains, there are many more: http://www.makeuseof.com/tag/vpn-tunnel-set/. You cannot route across the Internet with static routes unless you have control over the routers that are routing. They run BGP and will direct your traffic to the valid IP you are incorrectly using in your private LAN.

I have such configuration for my network.
WAN:
ether1 10.20.30.5/24
LAN:
ether5 192.168.1.254/24 and 192.168.10.254/24(DHCP)
I have Created Some queue for those ips.
I have to Access File/Folders from a Local Windows Server(192.168.1.2). When i access file/folders from the block 192.168.1.0/24 everything ok. But when i access file/folders from the block 192.168.10.0/24, it Showing on Queue and get very slow access.
I want to access File/Folders like 192.168.1.0/24 block if i use ip block 192.168.10.0/24.
Extremely Sorry for my poor English.
Give the Mikrotik an IP in the 192.168.1.0/24 subnet such as .254.
/ip address add address=192.168.1.254/24 interface=ether5
Tell servers in the 192.168.1.2 ip range to use 192.168.1.254 as the default gateway. Check that these servers can ping the clients in the 192.168.10.0 range. All file server traffic between the subnets will be routed by the Mikrotik. I believe this arrangement will work however I have been unable to test the routing for myself.
I recommend moving the 192.168.1.0 and 192.168.10.0 subnets to different ethernet ports if isolation is required. If it is not required then you are much better off using a single subnet to encompass all the devices. You could expand the subnet mask to 192.168.0.0/20 which will include 192.168.0.0-192.168.15.255 for example.
I've gotten a simple solution.
I just Mark Packet all of my Local Subnets. Then Assign High Bandwidth(500M) on Queue List.
Now, All users can communicate will full speed. :)
You can try
ip firewall mangle add
chain=prerouting action=mark-packet new-packet-mark=Local passthrough=no
src-address=192.168.0.0/16 dst-address=192.168.0.0/16 log=no
log-prefix=""
queue simple add
name="Local" target=192.168.0.0/16 parent=none packet-marks=Local
priority=8/8 queue=default-small/default-small limit-at=0/0
max-limit=500M/500M burst-limit=0/0 burst-threshold=0/0 burst-time=0s/0s

Do I need to forward these ports? Is there a way to do it on Windows 7? I've tried using a program named smart port forwarding but it crashes when the program is running. Thanks in advance.
You shouldn't need to forward those ports in order to be able to run the applications. Chrome and Steam are connecting through those ports to the internet because they are ones that the operating system says are available for outgoing connections and provided them with that unique port number when each application asked for it.
These applications should all run fine for you, without needing to open any ports. Opening a port is most always to let incoming traffic be accepted, not for outgoing traffic to be stopped. A telltale sign that a port is not open is that no connection can be made. If you tried to connect over the internet (port 80) to most random IP addresses, you won't be able to find anything, because the device at that IP address rejected your attempt to open that port to them. So because you are (I am assuming) able to successfully run both Chrome and Steam and have them be able to connect to the internet, you shouldn't be facing a port forwarding issue. The port numbers are just assigned essentially at random each time that an application needs to open an outgoing socket. (this being a simplification of the whole paradigm, but hopefully enough to be able to answer this question).
Edit: And yes, like #Rumesh-Eranga pointed out as well, port forwarding is done at the router level (on the internet router itself) and not at the computer level. It's a way of saying to the router "alright, any time this network receives a request to open port XYZ, send it to this computer that is connected to our local network."

How can I add a port to 127.0.0.1? I have 127.0.0.1:5984 open but want to open another one. Any idea? As A head's up I'm new to computers. I'm on a Mac running OS X Mavericks. I'm also on Xfinity.
Edit: I am having a port conflict while attempting to use CouchDB, how can I resolve this?
A port is a listener for a specific protocol such as tcp or udp. In order to open a port. You need a program or service to listen on that port. For example, by default Skype will listen on port 80.
Please read the wikipedia page for a basic overview or what a port is.
In computer networking, a port is an application-specific or
process-specific software construct serving as a communications
endpoint in a computer's host operating system. A port is associated
with an IP address of the host, as well as the type of protocol used
for communication.
http://en.wikipedia.org/wiki/TCP_Port
Edit: To answer actual question:
Unavailable Port
Problem
$ couchdb Apache CouchDB 0.9.0a747640 (LogLevel=info) is
starting. Failure to start Mochiweb: eaddrinuse {"init terminating in
do_boot",{{badmatch,{error,shutdown}},[{couch_server_sup,start_server,1},{erl_eval,do_apply,5},{erl_eval,exprs,5},{init,start_it,1},{init,start_em,1}]}}
Solution
Edit your /etc/couchdb/couch.ini file and change the Port setting to
an available port.
Excerpt from:
http://wiki.apache.org/couchdb/Error_messages
You can change the port CouchDB listens on by editing its local.ini file (which is in /usr/local/etc/couchdb by default). Under the httpd section, uncomment the port entry and change its value to the port you want to listen on (5983 in your example).
