VPN: Server 2003 or IPCop

[TiziteLayinLow]

I am tryin to setup a VPN for my class lab.

First question, will I NEED 2 nics to get this accomplished?

Second, which would be easiest microsoft server enviroment or IPCop 1.4.6

any input is appreciated

I've never used IPCop so can't comment on that.
If you have a MS 2000/2003 server box it's very easy to set up VPN. You need only 1 NIC if it's not at the edge of your network. (like acting as the gateway between your inside and outside networks)
Most docs on the Internet are for the 2-NIC configuration, for the 1-NIC setup, see step-by-step guide

ipcop is very easy, and free. And will run on much lower spec hardware than the MS equivalent. Give it a try, and if you can't work it out, then feel free to spend a fortune on stuff you might not be able to figure out either 😛

this is a lab project... all software is provided by the school. Ive been following the technet step by step on the ms vpn but it has me into 4 servers and i just think its overkill. to demonstrate the vpn i wont even be doing it over the internet just over the LAN to show what you can do. I dont know if i can simulate a DMZ with the access that I have. I might be able to possibly do it over VLAN but I dont think the network admin of the school even has it so VPNs can pass threw.

any more suggestions are appreciated.


edit: i followed that tutorual.. works great.. now my issue is this I have a cisco c831 router.. i am running class a internal IP addresses (10.10.10.0/24).. when I set static IP addresses in routing and remote access snap in its assigning 10.10.10.0/32 .. will I have an issue with this talking to my networks at 255.255.255.0 ? also - does anyone know the ports for VPN so I can forward them in my router to allow VPN over the internet now?

Follow the step-by-step guide Cooky posted. It only requires one server and one NIC and it's very simple.

You need to open TCP 1723 and 47 for PPTP VPN.

Edit: I think the /32 mask is normal.

I forwarded them in NAT and allowed in ACL. Is there anything else because trying to get in externally I'm getting Error 721: Remote computer did not respond.

Thanks for the help,

ok i found out what the prob was - i had 47 and 1723 tcp forwarded in NAT and ACL, but I needed GRE IP Protocol 47 in allowed in the ACL. I am going to try to take out the 47 tcp and see what happens because thats probably not needed.

thanks guys, matt

Yep, 47 TCP is not needed.

Here's some info.
