After making the same mistake, I think you don't need a bridge: could it be that your 2 instances of lwIP are running with the same MAC address? This is not covered by the netif used with the win32 port: you have to change the MAC address for pktif.c at line 131 to prevent using the same MAC address.

First of all, your mail is very difficult to read if you mix such long code passages with the actual questions you want to ask. Chances you get a response are higher if the problem is expalined shortly and code is put at the end of the mail.

As to your problem: I don't really know why this doesn't work, I already did such a setup on my PC. Did you try your client application to connect to some other (non lwIP) server? Maybe even outside your PC? If you still have problems, you can try to use wireshark to monitor the ethernet packets sent on the network. Maybe that helps to find the problem.
