VPN Failover

Is it just me or when setting up a S2S VPN with 2 ISPs at each end, it would require 4 SEPARATE VPNs to cover all failover scenarios and would this even work?

i.e.

Site A ISP 1 - Site B ISP 1

Site A ISP 2 - Site B ISP 2

Site A ISP 1 - Site B ISP 2

Site A ISP 2 - Site B ISP 1

In theory the last 2 VPNs are optional, but in the real world, I want the primary ISP being used at each site wherever possible because due to the secondary not having the same bandwidth.

Am I missing something or is there an easier way to do this?

If you want to keep up all tunnel at the same time, yes you need those 4 tunnels.

XG can also use IPsec Failover groups, which will rebuild the same tunnel with another Interface. https://docs.sophos.com/nsg/sophos-firewall/18.0/Help/en-us/webhelp/onlinehelp/nsg/sfos/concepts/VPNFailover.html

Ok but would I still need those 4 VPNs with the failover groups or do those negate the need for the extra VPNs? I don't need all 4 up at once I just need to cover each scenario of one failing.

If so it seems crazy as I have 4 other sites and they all have the same setup, which means instead of 5 VPNs at each site I need 20. That is 120 VPNs for what is a very common setup.

Coming from SonicWall I wish the VPN policy just had a fail over VPN IP built into it. This would simplify things massively.

Basically the SonicWall equivalent is Ipsec failover groups. Take alook into it.

I will do again but from first look I still need to create separate VPNs for each scenario, so whilst Failover groups might do what I need, it doesn't make life any easier. Or is that not the case?
