I just picked up a LinkSys WRT54G router/WAP. It's a version 5 model, with the 1.0.0 firmware.
It seems to be dropping idle TCP connections, in particular idle ssh sessions, after about 15 minutes. My previous router/WAP didn't do this. I can't find any documentation about how long NAT translations should take to time out on this router, or any way to see active NAT connections or increase the timeout.
Does anybody know if the WRT54G drops idle TCP connections this quickly, and if so how to fix it?
