Hi Winston, Is this a back to back config with the ISA firewall is the internal firewall? Or is the black box on the inside and the firewall is the external server? Thanks!

When I put the firewall box in place my clients are not able to surf. The ISA external gateway ip address is the ip address of the firewall box. Is there any extra settings I have to do in ISA to allow my client to browse the internet? The clients are configured as firewall clients. The firebox has three Ethernet ports (WAN, LAN and DMZ). The E/0 from the router connects to the Wan on the firewall box and the LAN connects to my internal switch. Thanks.
