Zsolt,

  What's the basic setup for using OpenVPN with a bridge?

Thanks,
George

It is generally a pain in the back to establish connections to bridge servers in a NAT -ed environment. Port forwarding is one of your options, however there are a number of issues: 1) A large number of ports may need to be forwarded depending on the bridge setup and how many bridges you want to access (security implications); 2) Some older Cisco firewalls without a decent GUI may give you a hard time to create the appropriate rules to do what you need.
 
My suggestion is to forget about ports and use OpenVPN on the bridge and the client machine to go through the NAT -ed network and everything in between your computer and the bridge. We have a significant experience with this and pretty good results. Your absolute expert (who came up with the combined bridge/Open VPN server solution) is Joe Stone (stone004@xxxxxxx). I can also help, if needed.

Subject: [AG-TECH] NAT and bridge traffic

Hello,

  Could someone with experience in this area  tell me the issues/problems with receiving traffic from a bridge server if I'm behind a NAT.  I've looked through the ag-tech mailing list and there's talk of problems but I can't find specifics.

Thanks,
George
