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.

Have you tried a "working" PC in the both topologies, and a "failing" PC in
both topologies? 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.
