I am attempting to publish TSgateway services from my Sonicwall NSA 3500 directly to my internal TSgateway server. We are trying to phase out our ISA 2006 server, so I'm testing just changing some of our web publishing rules on the Sonicwall to go directly to our internal server services.
I have changed the rules to go from WAN to my internal network interface. I believe my firewall, and NAT rules are correct. Problem is, it doesn't seem to work unless I change my TSgateway server default gateway to the Sonicwall ZONE IP address that is assigned as my internal network.
Maybe that's the only way these will work, not sure. My ISA must have been handling the routing with my previous setup, even though my ISA server isn't the default gateway for any of my internal PC's. Is this how it works by design? any help is appreciated, thanks!
