Probably not the best list to ask this on, but it's the closest that I'm subscribed to... I have several customers who use VPN (Windows PPTP) to connect to their Corporate networks. The first was sitting behind NAT on a FreeBSD router. The PPTP did not work. I moved them out of NAT and onto a regular IP, and it worked fine. I then swapped out the FreeBSD box with a Cisco 2620 and again tried the PPTP via NAT, but still it wouldn't work. Another customer is behind a Cisco 804 and his PPTP also did not work when his network was behind NAT, so I have to assign a static subnet for him. From home, sitting behind NAT on my Netgear router, I can turn up PPTP connections all day long. What gives with FreeBSD and Cisco's implementation of NAT that PPTP doesn't want to work?
