It's been in service for the better part of 10 years (originally 2.0.5 or so). It's acting as a router/nat device for a network with about 50 desktop systems, and has never given me a problem until this week. It seems that VPN (PPTP) won't work behind NAT. I can use VPN tunnels from XP PRO to both windows servers and linux-based VPN servers all day long from home using my netgear broadband router, but from this location, behind the FreeBSD box, they won't work. What gives? -- -- Troy Settle Pulaski Networks 866.477.5638 http://www.psknet.com
