    Hi all,

    I have a problem that I am stuggling with, and need some help please?

    Here is what I have:

    3 leg ISA configuration, external IP, 192.x.x.x for DMZ and 10.0.0.1 - 10.0.7.255 for the internal network.

    IThe internal network split in two, Site A IP range 10.0.0.1/22 and Site B 10.0.4.0/22 with a router 10.0.3.1 and 10.0.7.1 inbetween. 

    ISA internal IP address is 10.0.0.1 located at Site A.

    Client PC DHCP default gateway is 10.0.0.1 (ISA Server) at site A and 10.0.7.1 (router) at Site B.

    What I would like to do, or should I say, have to do, is to direct all traffic destined for site B to be routed via ISA to the router for site B (10.0.3.1).

    At the moment, we are planning to replace the existing firewall and do an inplace swap, therefore keeping the exitxting firewall static route. I am trying to preconfig ISA so that we can just unplug the old firewall, and pop in the ISA server.

    Does anyone know how to route all 10.0.4.1/22 traffic through a specific router?

    Thanks,

    Amathus.

    Hi,

    create a route with route add -p for the network with the destination!

    Hi Marc,

    Thanks for the pointer; Easier than I thought! I have added all the outher networks (172.x.x.x) with "ADD ROUTE" and also needed to add them to the Internal Networ list of ISA and they work a treat! Trafffic going where it is suppose to!

    Thanks again!
