VPN

By vpierce ·
I am trying to set up a VPN so that salesmen can connect to our servers via their ISP.

I have configured the server for RAS and added the needed vpn ports. I have configured them to accept incoming calls using tcp/ip protocol only.

I have configured my Unix box to allow pptp traffic through on ports 1723 and 21.

I have configured my Win95 client to dial an ISP and then dial the VPN server. I made sure the client had the latest Dun1.3 and vpnupd.exe. What I am not sure about is how to configure the DUN for the VPN server. What do I need to use as a phone number?

Is there any thing else I need to?

Please help.

1. There is no need to open port 21, since port 21 is only for Telnet, (unless you also have telnet open)
2. What to use as the phone number:
First make sure that in the network properties VPN Dial Up adapter is listed. If it's not, click Add > Adapter and choose VPN adapter.
Then when you create the new connection in Win9x, make sure that in the device list you choose the VPN adapter. For the phone number enter, either the PUBLIC IP Address of your server, or a host name which can be resolved by your client (i.e. vpn.mydomain.com) and points to the VPN server.

My VPN server does not have a public IP address. We use the Unix box to get out to the Internet so that is the only box with a public IP address.

So if you use PAT (port address transolator), which forwards the packets address to a spicific port to a private IP Address, the public IP Address is that of your Unix Box.

How is the best way to configure my NT server as far as protocols are concerned and are there any traps I need to watch out for?

Answer2 is the correct one which applies for your situation. If you have only one Public IP and it is assigned to the Unix box.

The only options for you is to either configure PPTP on your Unix box, or configure port forwarding on the Unix box, which will forward all requests on the PPTP port to the Win NT box, which you have configured. Check out IPtables/Ipchains which will do the job of port forwarding for you.

If you have another public IP, then assign this IP to your windows box andyour problem is solved. For your VPN clients, then give the IP address of this box.
