ISA 2004 routing problem
Posted on 2007-07-25
I have recently inherited a network a client site to support. the setup is 2003 enterprise, with two network cards. one cooneted to the router the other to the private network. THis box hosts IIS 6.0, excahnge 2003, and has ISA 2004 installed. I have never worked on a server with everything on it at once so i am a bit confused.
Every few hours the ISA server starts giving the following errors
ISA Server detected a proxy chain loop. There is a problem with the configuration of the ISA Server routing policy.
ISA Server detected routes through the network adapter Internet that do not correlate with the network to which this network adapter belongs. When networks are configured correctly, the IP address ranges included in each array-level network must include all IP addresses that are routable through its network adapters according to their routing tables. Otherwise valid packets may be dropped as spoofed. The following ranges are included in the network's IP address ranges but are not routable through any of the network's adapters: 0.0.0.1-18.104.22.168;22.214.171.124-126.96.36.199;188.8.131.52-184.108.40.206;220.127.116.11-18.104.22.168;240.0.0.0-255.255.255.254;. Note that this event may be generated once after you add a route, create a remote site network, or configure Network Load Balancing and may be safely ignored if it does not re-occur.
restarting the firewall bring the service back online.
the isa setup specifes the LAN card server as the internal network, Am i missing something obvious to change?
thanks in advance
