I actually had this problem between a Linksys and Lucent.  I had 2
Linksys's talking to one another just fine but as soon as I put the
Lucent in the mix, I couldn't get the linksys's to talk to it. After
a bit of futzing around, I finally managed to get it to work but I
can't for the life of me remember what I did.

But the symptoms were almost identical.  I could see packets from 
the Lucent using tcpdump and I could see the return packets going
back out but a tcpdump on the laptop with the lucent only saw the
packets going out but nothing coming back.
