Losing DHCP Gateway

Larnel Hight

This problem started with 17.5.0 GA.  The firewall is handling DHCP for my lan.  Users have started to lose the default gateway(the Firewall) randomly throughout the day.  I have to either reset the switch or the desktop network adapter in order to regain internet connectivity.  This does NOT happen to all users at the same time.

I updated to XG 115 SFOS 17.5.5 MR5 but the problem still exists.  This actually introduced another problem of not being able to access the gui from Sophos Central, but that's not as pressing.  Any thoughts on this would be appreciated.

Thanks

Larnel

    The same thing is happening to me with 17.5.7,  However, I just switched to Google Fibre who changes the public ip every couple of days or something.  I thought that was the problem and Sophos was not picking up my new public ip and it could possibly be the problem because I lost connection after I rebooted the modem and I am guessing I got a new IP at that time.   It happened again this morning and I did not do anything but again maybe I got a new IP overnight.  Guess I will start tracking that.   So after I didnt have connection in the morning, I rebooted the Sophos and did ipconfig /release and renew and this fixed it.   Next time I will just to release renew to see what happens.
