Hi!

I have a proxy server in my office, with two NICs

One is connected to the broadband ADSL Modem (not router), and has been given the IP 192.168.1.xxx and the ADSL modem as gateway (192.168.1.1)
The second has a local lan IP, and is connected to the local LAN, and has a leased line router IP as gateway.
The machine is running Windows XP, with Symantec AntiVirus 10.1
I have a regional office with a VPN server running
I can connect to this VPN server from home.
I can connect to this server from office when I transfer the ADSL connection to an office pc with one lan card.
I am unable to establish a connection to the VPN server from the proxy server.
I tried disabling Windows Firewall: but it did not help.
I tried removing the gateway from the local lan NIC, but this did not help either.
I tried adding a route : dest = vpn server IP, mask=vpn server IP, gateway Broadband NIC IP/ADSL Modemlocal IP/Broadband gateway/broadband static IP. Did not work.

I seem to be missing something while establishing a Split Tunnel. There are security issues to be addressed: but only if the VPN connection is made.

No ports/exceptions have been created: since I was able to successfully connect from local machines without doing any such thing.

Request advice: and I would be most disappointed if I learn that it cannot be done.

Oh: I got the problem.
I have two Broadband connections: one with a wireless router, and one with an ADSL modem direct, so that there is one connection as standby always.
The router requires NATting to allow VPN, which I learnt after many failures and experiments at office and experiments at home.
One experiment at office was to try and setup FreeProxy on the proxyserver, so that I could VPN from lan machines. This port had remained, and maybe was not configured correctly. So FreeProxy may have been listeneing at 1723 and not responding properly.
Neither connection could work on the proxyserver, while the direct modem worked on other machines

I deleted the port, and was able to connect.

I now have some more questions: I am not sure whether I should open a new thread: pl advise.
1) I entered a random (valid) IP address in the 'Use the following IP address') field of the VPN connection. Have I achieved anything? The address I have entered is a Class C address. Should it be a Class A address? Will any address at all prevent bridging between the VPN and the local (my office) LAN, or between the VPN and the VPN server LAN?

Request advice: I intend to use this VPN to replace a P-to-P leased line that I currently use: and to establish inter-office communication.
