Hello, we have Sophos UTM and Sophos RED15 on remote site. Last days I am facting trouble that when RED15 is turned off and started again it is connected to our UTM but can't ping on RED site and they are not able to reach the internet. We are Using Standard / Unified Mode. I set it up according to this tutorial Sophos UTM: Putting clients on RED and LAN onto same network. It was working for a few month allright, I don't know what is happening now.
