Re: [PLUG] Speaking of VPN....


Check out OpenVPN. It works happily with a tunnel or tap interface, so you can route whatever you want across the tunnel. It uses UDP or TCP for L4 encapsulation, so it's easy to manage through a fiewall.

I use it all the time and it works very nicely. As it supports certificates for authentication, it can be initiated remotely without user intervention as required.

So, I have a question about choosing a VPN implementation.

Here's my situation:  I have a machine sitting behind a NAT firewall that I can't modify or configure.  In order to access that machine and it's services, I create an SSH tunnel with several port forwarding rules.  I would like to change this.

I would like to use some sort of VPN that keeps a persistent connection between my router at home (running Ubuntu) and my remote machine.  Here are some of the behaviors I would like to have:

1.  From home, I would like to be able to access the machine as if it were on my local network.
2.  During the week, I work from the remote machine's LAN.  I would like for this machine to continue to work normally on the remote LAN.
3.  I do not want the remove machine to forward all traffic to my home network.  When it needs to access the internet, it should not route through my home connection.

I've been struggling to figure out which VPN package would allow this.  Any suggestions?

Thanks for the help,
Brian
