Hi

I have a NSG100 with fixed internet line on WAN1 and an LTE router which is the backup line on WAN2. The problem is that when I take down the line on WAN1 the VPN will not come up again via the LTE line, when I connect the line at WAN1 again the VPN comes up again after a few seconds.

I have configured WAN1 as primary port and WAN2 as backup line in traffic shaping and set WAN load balanching to Failover.

Any solution to the problem?

    Did you configure Outgoing Interface as "Auto" in site-to-site VPN page?

    We are doing the same exervice at a customer later this week.
    This is a supported configuration? with a secondary wan which should failover?
    how is the failover policy? will it kick to wan2 only if we miss the link on the wan1 interface or is there a ping policy on the wan1 interface?

    The failover mechanism is once the link status has changed (ex: link down) then it will move to another WAN interface.
    Or it can work with WAN load balancing algorithm (Failover) in traffic shaping,once the ping fail it will also use another WAN interface.

    You will need to take a note of the Public IP obtained via 4G, then manually add the IP in the NAT traversal section under Security Gateway>Configure>Site to Site VPN. Just remember to remove once WAN1 is back up :-)
