Publish Sharepoint with ISA behind firewall

[Matt_Tate]

Hi all,

 

i've been trying on and off for a while trying to get this to work but keep giving up as i just cant get my head around it - i'm back to trying again now and looking for some help in my quest...

 

first a bit of background

 

we have a sharepoint site (with SLG) that is accessible via our website on a seperate public IP - authentication is by basic authentication.

 

we have a Sonicwall firewall that does all the NATing, firewall features, security etc

 

we also have an ISA sever onsite with one NIC that we use as a proxy server.

 

how can i get our sharepoint site to use FBA via the ISA? my thinking is

 

sharepoint site (External)-> Firewall -> ISA Server ->sharepoint site (internal)

 

if im correct how should i configure? allow the firewall on the external address NATed to the ISA? then NAT on ISA to the internal sharepoint site?

 

help would be great...its been killing me since last Jan!

 

Cheers
