I have tried simhost sample. I found that ping works because low_level_init() is executing ifconfig to add the ipaddress for tap0.
But, no code from simhost ever gets executed. the read on "/dev/net/tun" does not get any data.
I have got 2 suggestions, whose feasibility I do not know. Please comment.
1) Create a bridge between eth0 and tap0
2) instead of tap0 do the read and write of packets on eth0.
To answer your first question, I have sample client-server application using the regular Linux stack working perfectly fine.

I'm not sure what the behaviour would be when the interface is firewalled.

Do you mean you have a LWIP sample running or using the regular Linux stack?
Have you tried running the simhost sample in
contrib/ports/unix/proj/unixsim? If not I would suggest you start there.
Run the simhost application and attempt to ping the host at 192.168.0.2.
