No Internet when WAN1 fails and Site to Site VPN Drops on WAN2
We have a setup and site to site VPN with Sophos Firewall on Azure Cloud, so what happens is that when the WAN1 goes down, the internet failover on WAN2 for which the DNS/DHCP is done by the Meraki but we have a VLAN where the DNS/DHCP is done by the local domain controller. and Internet does not work when WAN1 fails over to WAN2, However, I get the constant ping on google.com but no internet.
VLAN 80 I am having the problem with the internet connectivity when it fail from WAN1 to WAN2
VLAN80 Client addressing - Do not respond to DHCP requests
