I am using SA Ent. v8.0.2725. We have a Cisco router that determines local vs internet vs VPN bound packets. It directs 172.17.x.x packets to the Sophos FIrewall which in turn send them across the VPN.
SA shows red with a "NOT OK" status. --------------------------- Bob Hartung, Dir of I.T.

How are you forcing SA to go over the VPN? What does SA show as error for the down?

On my end we are on a 172.16.x.x subnet and at the other end it's 172.17.x.x. I am using Servers Alive (SA) to ping test 10 different devices on the 172.17.x.x end of the VPN but SA frequently shows that the devices are down when they actually are up. I have SA configured with the Sophos UTM ping test as the primary connection and then the rest of the devices dependent on the Sophos being up. I have played around with the timeout value set as high as 25 ms on all the devices as well as dropping the success % down to 50 but I still am getting frequent false downs. I verify whether there's a down condition by command-line pinging or remotely accessing devices while SA indicates Down. I also have a ping utility called Ping Plotter that keeps a history of periodic pinging that shows ping success/fail as well as average response time which is roughly 75 ms and very infrequent fails. Any suggestions on SA settings that might fix my false downs? --------------------------- Bob Hartung, Dir of I.T.
