Configure your Linksys to pass the appropriate ports to the ISA server's 'outside' address. Here's an example given the following: 1.2.3.4 - live internet IP address 192.168.1.100 - IP Address of External ISA 172.16.1.1 - IP Address of Internal ISA 172.16.1.2 - IP Address of Exchange Server Config the Linksys to pass all SMTP requests on port 25 to 192.168.1.100 Config ISA to accept SMTP on address 192.168.1.100 -> 172.16.1.2 Make sense?

ISA server cannot see the external or Public IP which is needed to publish Internal servers such as exchange. ISA server external NIC is assigned and Internal IP ( 192.168.1.x)by the Router. Is this possible or you have to have ISA external network card connected directly to the DSL or Cable Modem.
