We are exploring running two servers (one in the DMZ and one internal). We are using your high availability model without the load balancer.
What ports do we need open between the internal server and DMZ?
Is there any documentation on how to set this up?
Thanks a lot!
Internal connects outbound tot he DMZ. The DMZ never connects inbound to the internal server.
So typically that means no firewall changes as outbound is generally allowed. If needed, though, just pick a port for DMZ, and that is the outbound port from internal to DMZ.
