I have setup a site-to-site vpn using 2 ISA 2006 servers. I have setup rules on both servers to allow all outbound traffic from local host, internal, vpn clients, and each others isa network. I can ping from each ISA server to the other successfully.
From ISA1 I can ping any ipaddress on ISA2's network including ISA2
From ISA2 I can ping any ipaddress on ISA1's network including ISA1
The problem is that clients on each network cant ping anything on the other network. If I am on client1 on ISA1's network, I try to ping client2 on ISA2's network and get no reply. After looking at logging entries on ISA1 it says initiated connection and closed connection for the pings but I never gets replies.
Any idea what i'm missing?
