We've tried a PC that fails in the 1st topology and it works in the 2nd topology. We'll double check the addresses and stuff. I think you are right about Wireshark is seeing the packet but the stack is not passing it on for some reason but I can't figure out why.

If the "failing" PC fails both ways, and the "working" PC works both ways, check for a firewall program on the PC. If they both fail in one topology and work in the other, then check addresses and masks and stuff. It could be that Wireshark is seeing the packet (promiscuous) but the stack is not passing it on because of the mask or something. Also, just in case - I found that when Visual Studio is running a program, it can bypass a firewall, but then if you shut down VS and just run the program, you can have firewall issues. _______________________________________________ lwip-users mailing list lwip-users@nongnu.org https://lists.nongnu.org/mailman/listinfo/lwip-users This email may contain information that is confidential and/or legally privileged in nature.
