Configuring ISA 2004 for to allow access to WAN

[tosca925]

We have recently changed our IP set up away from the LEA provided. We are now on a 10.0.* range instead of a 172.*.

 

I have configured the Internet access and all is ok. What i can't work out is how i allow access to the WAN. We have a server on the WAN (in another school) that hosts stuff all schools access. This is still on a 172.* address. How would i set up ISA to allow me to get to this?

 

Trouble is i can't access it through the Internet front end either but all other http websites are fine?

 

 

Any ideas?

Are you accessing via it's IP Address or it's DNS name?
