Hi everyone I don't know if I am posting this to the right newsgroup but it 
is the closest I found,
in case you think you can advice me to another newsgroup please feel free to 
do so. I am so desperate to get my problem solved.

The issue is related to sockets and networking this is my problem

I have to build two applications(GenericCustomers.exe and 
PremiumCustomers.exe) they will run on the same server
both applications will connect to one server (MainBase) across the Internet 
using the same port number 1323
we have two external IP addresses i.e.(Internet IP address) and pointing by 
the router to the my server where my applications are running
I need GenericCustomers.exe when connecting the MainBase should use one 
external IP address while PremiumCustomers.exe should connect using the
other external IP address.

The MainBase server recognizes applications by their external IP address 
which have to be registered in it's database


I can not run each of them on a separate server neither I can use different 
port number (otherwise it can be solved by the router)
I am using C# and visual Studio 2005

What I see is that the application when attempts to connect should 
initialize the socket with the IP address that I want to start the 
connection with
I can not see this as impossible (think of the router applications that do 
all the NAT)
but I did not see anything that help in the socket class nor on the Connect 
method..

guys anyone have encountered such need or can solve this .. please write 
back
