The latest maintenance release (MR15) for SFOS v17.5 is now available through the MySophos licensing portal.
To install, you can download the firmware from the Licensing Portal. Please refer to Sophos XG Firewall: How to move to a different firmware version.
is the "NO DHCP and ARP Cache coruption" be fixed in MR15 for the RED60 devices?
Hi, can you explain a bit more, what are you seeing? We have an SD 60 (two actually, we replaced the hardware with a spare we had, happens with both of them) What we see is that regularly (between every few hours and a few days) the RED tunnel is still online, RED external IP pingable, but no traffic coming in from the LAN, at least it does not reach the redsX interface on the XG (18.0.3). The RED has to be rebooted.
The Sophos case has been going on for two months. I''ve been suspecting a problem on the LAN side (maybe even a customer problem), for a while, so what you are describing sounds interesting.
