Bridged OpenVPN

[Peter847]

I want to bridge two remote LAN’s into one logical LAN and would like to make sure I’m thinking the right way before I start reading up on the details.

I currently have two physically distant networks both running pfSense and connected together through an OpenVPN tun interface.  I want end up with one logical LAN with two gateways, one in each physical location.  Each device is assigned a default gateway typically the one in the same location as the device and, additionally, outgoing packets are routed to a specific gateway according to their destination.

Here is how I think I should set this up.

• Change the OpenVPN to a tap interface.

• Assign fixed IP’s to both the pfSense LAN interfaces in the new subnet address space.

• Disable one of the DHCP servers and use the remaining DHCP server to set the default gateway according to where the device is located.

• Add routing rules in each pfSense to redirect any packets to the WAN interface nearest their destination.

Before I start reading up on all of this, am I thinking along the right lines?
