Hello, i have a back to back isaserver configuration with external ISA protecting our internal network and then an internal isa protecting our production network. I'd like to be able to VPN into both of them. So what i thought is to setup 2 static IP addresses on external interface of front end isa server and then publish the internal ISA on one as PPTP server to allow access to our innermost network and use other IP address to access our internal network but this is not working. Does anybody know why and if there is a solution for this?
thanks

Hi Fabrizio,

That won't work. But what you could do tunnel within a tunnel if you need to VPN into the back-end ISA firewall from the front end.

HTH,
Tom
