Please help, I'm banging my head on this one. I started to get these after a new installation of ISA. The ISA Server services cannot create a packet filter 64.253.196.251. This event occurs when there is a conflict between the Local Address Table (LAT) configuration and the Windows 2000 routing table. Check the routing table and the LAT to find the source of the conflict. Ok, so I check technet, and it says there is a conflict between the LAT on ISA and the route statement in ISA. Now 161.111.195.111 is the connection that is external. 161.111.195.226 is the internal connection. Both use 161.111.195.1 as the default gateway. I also get numerous reports saying the gateway has lost the connection to the server when browsing. Please assist if you see my error. =========================================================================== Interface List 0x1 ...........................
