TCP traversal for a web server behind a NAT , is that possible?
Hello,
I'm developping a web server which will run behind a NAT . To make it
easy-to-use , I'd like to implement NAT traversal automatically . And
I'd like to have the web browsers outside visit my web server directly
(I mean the mapped address on my NAT,without the help of a proxy that
has a public IP,for bandwidth concern). Can I achieve that with the help
of PJNATH and just one or some STUN servers? Is the usage of PJNATH
limited to P2P applications?

You map port 80 in the NAT router to port 80 of your your web browser
and it should work. What are you trying to achieve really?

Hi,
you can use PJNATH to traverse NAT only for UDP transports.
STUN has been designed to map UDP transports only.
You'd be able to find your public IP address by just creating a temporary
UDP socket and sending Binding request to a STUN server.
But however, you cannot find the mapped port of your web server with STUN,
since it uses a TCP socket.
Interestingly, there is something called STUN for TCP(STUNT). you can check
this http://nutss.gforge.cis.cornell.edu//libnutss/0.1.0/index.html out
instead, which might suit your needs.

Sundar

What's the update on this topic. I'm pondering a similar problem.
Has anyone been successful with implementing pseudo-tcp-over-udp (either from libnice or gtalk jingle)
Please let's revive this discussion. I posted a similar question a day ago. But we can use this thread.
