2 VPN tunnels Active/Standby between 2 sites

[marcinw]

Hi,

Can we have 2 IPSec VPN tunnels between 2 sites (One SMB 1550 device and One GW 5100) in Active/Standby mode ?

I mean there will be only ONE Internet  link from SMB 1550 of course (But 2 VPN profiles) and TWO Internet links from 5100.

If yes does it work only with IKEV2 and Dead Peer Detection or also the other mechanism on IKEv1 ? Are there any other restrictions or generally how does is work ?

Nobody has idea if is possible having 2 vpn tunnels in Active/Standby mode between 1550 and 5100 ?
