Site to Site tunnels not able to communicate with each other
We currently have two remote offices connected via site to site IPsec tunnels to our HQ. Our HQ SSG firewall has a site to site configuired for Azure. However the two remote offices are also connected, but cannot access Azure. I realize this could possibly be we may need to add a static route to each of the remote office firewalls, but im not sure.
I have tried several combinations including adding the remote Azure subnet as the Route and the Tunnel interface as the next hop, but I still cannot access anything from the remote gateways.
