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.
Have been having this same issue, have upgraded my firmware to 17.5 6 and have not seen the difference.
Aside, resetting the LAN card, is there any solution by Sophos yet?
run the following from Console,
console> system dhcp conf-generation-method old
Thank you for your response, Please how do i revert back to 17.5 as the earliest version on my dashboard is 17.5.5 MR -5
is there a way to download firmware and directly upload to XG ? Share link Please
Do we have an update to this issue yet ?
