I have created a supposed L2 bridge between two remote sites, yet I get truncated results on the client end. Using pfsense and OpenVPN.

Every request on the server side I can watch in realtime get received incomplete on the client side... help!

I tried:
setting mss at 1200 on all interfaces had no effect, same errors.

I always seem to get bytes missing on the remote side of the l2 bridge.

Pls help shed some light on this.
