Then why is it in the table? Maybe it should again be considered to add a mandatory field to a gateway registration with a net-44 IP that should be pingable via the tunnel (e.g. the IP of the gateway itself) and run some very infrequent ping to that address from a monitoring system that is also on the tunnel network (not amprgw as some people apparently choose not to tunnel to that system). When e.g. one ping per hour is made and nothing is heard for 7 days or even more, the gateway can be marked down and removed from the encap.txt and RIP broadcast. The operator can then re-enable it via the portal. Rob
