How to handle IP Address rerouting with .NET Remoting

Question

I have a process within a network that wants to talk to a service on another network. So I have two computers:

Client                            Server
172.X.X.X  reroute-> 172.X.X.X to 10.0.1.X

With this setup, I can call the Server with the 172.X.X.X ip address and it maps to the 10.0.1.X address and talks fine. However, when I try to use .NET Remoting and communicate, I get an exception:

System.Net.Sockets.SocketException: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond 10.0.1.240:8196

How should I handle this situation? Do I need to switch remoting technologies or roll my own?

Answer 1

This is not possible with .NET. When you're having ip rerouting issues, switch to WCF.
