We have the following network configuration:
Outside: Static IP from ISP
Inside: IP Address: 10.0.0.1 (Static)
DHCP enabled for all other clients
Ouside: 10.0.0.2 (DHCP from Router: Resvered)
Inside: 192.168.2.254 (Static)
All clients allocated IP from SBS DHCP
Gateway set to 192.168.2.254 (PIX Inside)
This configuration has worked fine for the last 18 months without any problems. Now we need to enable remote access to Remote Web Workplace and we are implementing Exchange. If we remove the PIX then everything works fine (ports were forwarded to the SBS for this test). We have port forward on the router ports 443, 444 and 4125 to the PIX. I need help with the ACL's on the PIX to ensure that are then forwarded to the SBS server. I am unsure whether this is NAT or PAT and what the commands should be.
Any help would be gratefully received.
