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

    Hi,

    SFOS 17.5.7 MR7 on XG125 - regardless of the setting "dhcp system conf-generation-method" old or new - DHCP does not work properly, it is necessary to restart the interface on the client. Maybe MR1x will fix it? :)

    Actually, i would like to ask, if you can get a pattern of this Issue? 

    Are only certain Devices (OS) affected? 

    Because i can only observe this issue in my personal network (not my customer networks) and only my Windows Clients are loosing the Gateway. 

    None of my IoT Devices seems to be affected. 

     

    Maybe somebody can confirm this or give more details.

    On SFOS 17.5.7 MR7 Sophos Home licence

    iOS (iPad, iPhone) , Windows client are definitely affected. Those devices have static DHCP address on Sophos.

    But I couldn’t test all devices I have before changing it the “old” method

    Reverted to “old” method, all clients (iOS, Windows, MacOS,IOT...)work fine.
