I'm having a problem getting my VPN setup to work. I'm using the W2K
VPN server and XP client. I have the server set up to assign a fixed
range of ip addresses, I'm using PPTP, and I'm not using a RADIUS
server. I'm sure my user acct is set to allow remote dialup. When I
test my configuration on our local LAN, everything looks ok, as far as
I can tell. I get authenticated, I can tell an IP address has been
assigned, etc. However, when I try to connect from outside our
firewall, the connection stalls at the "verfying username and
password" stage. I get a timeout w/ error 721 and the message that the
remote computer is not responding. The firewall is set to allow tcp
1723 to the VPN server. I may not understand something basic about the
way VPN works. The way I understand it, all traffic by the VPN client
is tunneled thru 1723 to the VPN server, which passes it on to the
network. The server also responds to traffic intended for the IP
addresses it has assigned, and routes it thru to the clients that have
established connections to it. However, it's like some traffic isn't
going thru the tunnel, and is blocked by the firewall. Is there
something I'm missing here? I'd appreciate any input as to how I can
get this to work.
