Hello,
We have deployed Sophos SD-RED 60 to our Office 4. This RED is currently connecting to Office 1. We have established SSL VPN tunnel between Office 1 and Office 2 where Office 1 is acting as server and pushing networks deployed at Office 4 as local networks.
We are considering second VPN tunnel between Office 4 and Office 2. We would use it for failover or better for load balancing. My question is about routing and to consult pottencional issues, I am afraid of loops.
Let's say Office 2 would like to access network of Office 4. This network is reachable through SSL VPN tunnel to Office 1 or directly to Office 4. Is direct connection always prefered? What about packets going back to connection initiated by Office 4?
In the future we plan to replace firewall at Office 3 to be SD-RED as well and this would connect to Office 1 and Office 2 for load balancing.
