Only one VPN connection at a time

By ashleypursglove ·

I have set up a vpn to windows server 2003.

The VPN connects fine for each client but for some reason, as soon as one client is connected, no others can connect and recieve a 720 error.

I have read a few posts on the interenet that suggest this could be an issue with the firewall only allowing one VPN connection through at a time.

Please could someone give me some advice on how to confirm if this is the issue or not or if I have something configured incorrectly.

Kind Regards

Hi Robo,

Thanks again for the help.

DHCP is not enabled as i found that when It was no client could connect. I have manual IP in operation with 100 ips available.

Yes I have more than one simultaneous connection set up as described in that post. I have 128 pptp ports.

Also one thing to note, when setting up RRAS I had to go through custom setup as the server only has one NIC.

Ummm, I am pretty sure that is the issue

Since the server, by default, creates two separate and distinct networks, the internal and external network, I am not entirely sure it will work with only one physical interface.

but it's not recommended in any senario.

the easiest is simply stick another network card in the server. The server is going to act as a router in any senario, so seperate network cards is the easiest way to use Windows server as a VPN server.
