Hi, Having a bit of an issue with ISA2004 on a trihomed box ISA server has the following IP's203.x.x.x192.168.0.30192.168.1.2 The main network is on the 192.168.0.x subnet and this works fine however we are setting up a dedicated link to a remote office on the 192.168.1.x network. I have no problem routing traffic between any of the networks however the clients on the 192.168.1.x network cannot use the ISA proxy server on 192.168.0.30 - the traffic gets to ISA as 'unidentified traffic' using port 8080 in an allow rule, (this is the same if clients on the 192.168.0.x network attempt to use the 192.168.1.x as the a proxy) and the client recieves the 'cannot find server or dns' error. If the clients on the 192.168.1.x use 192.168.1.2 as their proxy then everything is fine. So I guess my question is, should clients on the 192.168.1.x subnet be able to use 192.168.0.30 as their proxy? Thanks.

Why not enable the web proxy on the 192.168.1.x network for clients in this network?

You can do this with the web proxy tab on the network properties...

It is enabled, otherwise they wouldnt be able to use it as a proxy.

The question was, should clients on the 192.168.1.x subnet be able to use 192.168.0.30 as their proxy? -- and if so, what might be preventing it.
