I have the uneasy feeling that this might be a one way switch (another undocumented feature). I know that it did not work until I switched it on... If any one has any ideas I'd sure appreciate it. I do not want to have to do a reinstall, I like my work but not that much!!!!

Try disabling the packet filter and see what happens.

So I decided to turn it off... Problem is it appears that you cannot turn it off again!!!! I removed the tick for PPTP out of the allow PPTP through the firewall restarted the services and tried a connection and I could still get out!!! OK try a reboot just in case I missed something.... I can still get out!!! OK delete the SecureNat PPTP rule completly restart the services and I can still get out!!!! OK try a reboot just in case I missed something.... I can still get out!!! Now I am stumped Is this a one way only switch? Am I doing something wrong? (probably)I have tried these things both on my Test server and on the Production server. Both are PS3 2000 servers with ISA stand alone running ISA sp1 and Hot fixes 174 and 256.... Any ideas??? Any help would be greatly appreciated...

Why? Because that client becomes a link between the remote network and my network. I have no control over the security policy on the remote network, and I don't know what this VPN client is transferring from their network to mine, and what its transferring from my network to theirs. ISA Server doesn't not examine communications going to a VPN link, so you have no idea what's going on.

It works well as I often connect to my home network using this. We use DHCP here at work and we use the ISA to authenticate out going traffic. I have inadvertanly discovered that I can VPN out on ANY computer that is NOT a part of the Domain. While the security implications are relatively small there is an issue with bandwidth being used. The ISA is the default gateway. The connection does not show up on the ISA server I cannot find an indication of the connection any where, but it is. Is there a way of stopping this?? Am I missing something simple?? Thank you for any assistance or advice that you can give on this.
