Hi all. I have about 50 Alix embedded firewalls running at branches. All the branches connect to a central pfsense at our data centre via an openvpn tunnel. This solution works absolutely beautifully and allows all the branches to be on one private network. The problem is some of the branches are in locations where the ADSL links have intermittent connectivty problems and can go down for extended periods. We have countered this by putting down 3G routers at these branches and having a Dual Wan with load balancing pools for failover. This works well and when one link goes down the traffic is routed via the other link. However this does not work for the openvpn tunnel that refuses to establish down the secondary WAN link, I have tried and tried but can not get it to work.
Can anyone shed some light on how to get this to work. This is a major for us, as the branches communicate down the openvpn tunnel to their financial app hosted at the data centre and if the tunnel does not come up down the secondary wan link it essentially renders the branch unable to do business. All help appreciated. Mark
