OpenVPN Support Forum

I have a bridged VPN between two sites on two Windows boxes. The server site is bridged, and the client site is bridge. All the hosts on the server site can see all the hosts on the client site, ie. one big LAN on one subnet (192.168.1.0/24). The routers on either side hand out dhcp to any client on any side of the bridge. I want dhcp packets to remain on their respective side of the bridge. Can this be achieved in a Windows OpenVPN environment? And how?

I would like to know if this is possible to block under OpenVPN as well since my workaround was to just isolate by MAC address in the router settings.

Thanks

Block the DHCP protocol using a firewall on the TAP virtual ethernet adapter on one or both of your OpenVPN servers.
