I have been trying to tackle a problem where I need to create a second VPN tunnel to a site (SiteA), this site already has a VPN tunnel set up with our VPN Gateway.
SiteA is unable to create a second tunnel to our VPN gateway public IP, as a route already exists.
I need to knnow can I add a second IP to the vPN gateway, which I think is a NO, but I can't find anything concrete to validate that, and if that's not possible, can we add a second VPN gateway into the same GatewaySubnet, in our hub vNET.
Although I think this would be problematic as how would the traffic from firewall know which tunnel to send the taffic to.
Some backgound: Hub and spoke design with hub consisting of Az firewall and Az VPN gateway. Peered spokes route through FW to get to VPN gateway. Hope that makes sense.
Thanks in advance.
