Ok, so I have a Windows 2003 member server that has ISA 2004 installed; which works great. But I'm attempting to set it up to allow for inbound VPN clients, I've gone through the reference papers and seem to have hit all the right configs, but when a client attempts to VPN in, the PPTP hits, but then I get an Unidentified IP Traffic error which is denied. I look in the logs and it's appears that the GRE traffic is being denied. Am I missing something here?

Where do I need to do that, since I have an access policy for VPN clien to internal network that has all outbound traffic. Is this an additional access policy to allow for GRE to the internal network?

mmmmmmmmmm .... i will have to check it out, i didnt try that trick on ISA 2004 , i have done it with ISA 2000 and it worked just fine .

try to define it like an Server publishing PORT 47 from the external nic to the internal ...... see if that works for you .......
