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?

How can I use ISA server in Integrated mode behind a Linksys or a Dlink
Router? 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.

Thank you,

Best,
