Im running ISA 2006 with a IPSec tunnel to a branch with a Linksys VPN Router. Tunnel works great but when I tries to reach a HTTP service at the branch I get a 500 error.
When I look at the logging in ISA I can se that the client now has become the public interface on ISA server, I can figure why its not working ;-)
I have tried to type in the branchoffice subnet in internal network properties but still no luck. I have also tried to create a "second" HTTP protocol without the Web filter but it doesn't work.
If I disable Web filter on the original HTTP protocol this works like charm but I guess you wouldn't like to do that...
Please help I'm panic over here!
