I am running NG FP3 on Win 2000 Server. I have 8 Static NAT addresses for web server, e-mail etc.. Approx. 12-18 hours after the server is running the Static NAT addresses stop functioning. No traffic in or out to those addresses. The hidden nat using the firewalls external interface works fine so I thought it might be a problem with the proxy arp. I have to reboot the server in order to get traffic going for the Static NAT addresses. Anybody have any suggestions?? Thanks.
