Not just firewalls, but my Netgear home router does the same thing.  More than 
a few times I ran nmap and then wondered why nothing worked again (until I 
reset my router).  And any SSH connections left idling through the router 
(either way) will eventually just stop responding and time out.

It will be replaced soon, so I will soon be unfettered by these limitations... 
yay!
