We are running a 1605r with 2 ethernet ports as a NAT router for a few clients. This had been working fine for over a year, then recently something strange seems to be happening:
The router will run perfectly for anywhere from 6-12 hours, then it becomes un-reachable via telnet. I can't ping it, and no traffic goes through it. If I reload the router, everything comes back up fine and runs for another 6-12 hours. I thought this was a memory issue, so I put a 16mb simm in it, and upgraded IOS to 12.2(10b), but still the same issues. I have been putting in "reload in xx:xx" statments a couple times a day so I don't have to drive to the location and physically reset the router every few hours. Here is my current config:

end
any help would be greatly appreciated. This isn't a bandwidth load issue, because there is only about a max of 400k/sec going through this at peak times.
