I am running two firewalls in an array, and am getting the following message from my 2nd firewall The ISA Server services cannot create a packet filter x.x.x.x. 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. When I check the routing table of the firewall reporting the error, I get the route 255.255.255.255 255.255.255.255 x.x.x.x x.x.x.x, where the x's are my external IP address. The firewall that is working fine lists the x's as my internal interface NIC. When I try to delete this route, and recreate it, it returns an error "bad destination addresss 255.255.255.255" How can I sort this problem out? J.
