All mac's disconnected

Hi, 

I've got an issue with all 255 of our mac's not showing connected in SEC. They were last seen by the SEC a few days ago. 

The clients are getting updates from our local update server (on the same server as the SEC), the SEC is downloading updates from Sophos on a regular basis without any problems. It seems to me theres a problem with the message router.

I've got connectivity to the serer via ip & dns. I've been table to telnet to ports 8192 and 8194 on the server.

On writing this message I realised that the day the SEC stopped getting messages from the mac's was the same day I installed the sophos av client on the same server as the SEC. I've just removed it and restarted all the sophos services on the server. Rebooted my client on my mac but the messages are still not getting to the SEC. 

Restarted the SEC server as well now and still nothing from the clients.

Router Log shows:
