tcplistener/tcpclient

I'v been using vb.net to learn programming and have be using it for a year, but socket programming is completely new to me, with that in mind:

so I have two program which use the tcplistener, and tcpclient to talk to one another.

when they both run and I enter my ip and proper port numbers they recognise each other and can pass messages to one another, however when I place my client-side program onto another network segment it cannot seem to make the connection.

I believe the problem may be oriented around perhaps not entering a subnet with which to help locate my computer...?

(Also the firewalls are both off on each computer as well)

Hello,
Same position with me,
I,m too new for this language.

Are you sure it is even the software that is having the problem...


Basically...from what I understand, it works fine on a network segment within the same subnet. But, will not work when it requires changing subnets...Honestly this sounds completely like a Port being closed/block on the router between the segments...

anyways...if you have more info, that would always be great
