We have a Cisco 1600 programmable router with 5 IP addresses for our business and it seem to be having an issue with one of our IP's no longer accepting traffic that has web, terminal services, and FTP all being routed using NAT to various servers for there respected tasks (Port 21 to server A, Port 80 to server A, Port 3389 to Server B). If I reset the router all will be fine for a few days and then the IP address in question will not longer accept traffic but the other IP address will be routing fine. Hoping someone might have a little insight to this issue.
