Setting up routing on your home network

Question

openvpn

Gentlemen, I have a home network administration problem that I don't know how to approach (let alone solve).

So, I have three computers at home connected via a router to a corbina (now Beeline Internet). Two of them hang on WiFi, one on a wire.
The router connects to the provider via L2TP (I don’t know if it’s important, I’m writing just in case).
All three computers have Ubuntu 10.10 Maverick Desktop installed.

Other than that, I have everything I need to connect to a corporate VPN (using OpenVPN).
Everything connects just fine, if not for one thing - only one client with my certificate can be connected to the VPN at the same time.

Accordingly, when I try to connect a second client with my own certificate, the connection is simply reset.
After some thought, I realized that I need to install the client on the computer that is always on, and connect all the others through it.

Yes, by the way, all computers have only one network card, so you can’t configure at least one of them as a full-fledged router, as I understand it.

And now, as they say, attention, question! How can I make sure that all computers can use corporate VPN resources at the same time?

Thank you very much for your attention!

The above is a very good solution. Only one more OpenVPN is not needed at all, a banal NAT is enough. However, if you don't want to route all traffic through one machine, then consider installing advanced firmware (like OpenWRT) on your router. At the same time, raise the OpenVPN tunnel on the router, it will be available to all machines.
