OpenVPN with Dual WAN
I created Load Balancing/Failover on pfSense with dual WAN, it works fine and I have problem with OpenVPN tunnel over it.
On pfSense I created double server side of OpenVPN for each GW (WAN and OPT), and when both liks are "Online" my client can connect without problems and tunnel is established (over WAN or OPT, depending of client configuration).
Meanwhile, when one of links goes "Offline" (for instance WAN) tunnel cannot be established over other link (in this case OPT), and vice versa.
Even more, for instance when tunnel is established over OPT (both links are "Online"), and WAN goes "Offline", tunel over OPT crashes instantly.
