 |
|
Hi everyone,
It is possible for two workstation behind a router (with one Internet IP) to connect to two different VPN server at the same port number at the same time?
Any suggestion or workaround are welcome, thank you.

Depends on your VPN.
OpenVPN is absolutely no problem. PPTP works too, as far as I know (at least with a recent kernel/iptables). IPsec could give you a headache as it's difficult to NAT by desgin. But in theory it can work. Never tried myself, though.

Could you elabourate on what I have to do in order to connect to the servers simultaneously? For example, how do I forward the ports in the router setup? And how should the workstations (behind the router) be configurated?

There's nothing to do. The connection tracking of iptables does all the work for you (at least for OpenVPN and PPTP).

I think you have misunderstood me. I don't have any VPN servers. I am only trying to connect to a VPN server on some company. However, VPN requires port forwarding on the router unless I have mistaken. Thus, the problem is how can I forward the same port number to two different workstation behind the router (according to the VPN connection)?

Port forwarding is only necessary when *you* run a server. As you have only clients your router does the work for you... if this router isn't a Linux machine and PPTP and especially IPsec don't work I'm afraid your lost

I see. Thank you for your information. However, what kernel option do I need in order for the router to work? Is there any other special iptable rules that I need to define in order for VPN to work behind the router. The vpn clients, however, are mostly Windows machine.
