Multi-WAN Active/Passive configuration

Hello Kiran,

By "active-passive," do you mean you are on an HA setup? Or do you mean you have one active gateway and one link as a backup link?

Also, could you share the specific error you're encountering? And what you’re trying to achieve on the setup. 

Meantime, here are the doc guides that could help you set up:

Hi,

This is related to an active/passive gateway setup, not High Availability (HA). When I use "Any" in the NAT rule, the site-to-site VPN tunnel does not switch over to the backup gateway. Please advise.
