2 IPSecs (site-to-site, with 3rd party devices) on the same destination


I'd like to know the solution when requiring two IPSec VPNs (site-to-site) on the same subnet at remote branch. I'm trying on the existing FW, it didn't allow to establish 2 tunnels on the same destination. Would be appreciate if you've any idea/suggestion.

    Do not create two tunnels, have all subnets going through the same IKE tunnel. You'll have one IKE tunnel with two IPSec SAs.

    The reason I want 2 tunnels is I need a redundant link(with separate provider in the same FW appliance, at HQ). Then please give me a bit how to enable 1 tunnel that can support 2 IPSec SAs.

    Use routed mode. One tunnel per pair of WAN links.

    Or fill in both public IPs on a "normal" site-site tunnel.
