Hello All,
I hope someone can help me with this quite interesting technical issue I am running into. I setup Sophos XG on my physical server 2 days ago. In this network I have multiple vlans connected from Sophos XG via a truck port to my switch. All other vlans work except one. 172.30.111.0/24 which is my mgmt network. On this network xg is the default gateway which is 172.30.111.1, I also have other devices such at unfi controller, esxi(172.30.111.10) and some other management tools.
When Sophos XG is plugged into the switch and esxi is not: from a workstation on that network I can access Sophos XG and all mgmt tools and ping everything except for esxi because it's unplugged.
Once I plug esxi in: my workstation can ping Sophos XG. But my workstation can ping esxi about half the time 50% packet drop. Esxi can't.ping anything on the network except for it self. If I do a trace route on esxi to Sophos XG the first hop is 172.30.111.10 which is the mgmt ip of esxi and then fails.
When Sophos XG is unplugged and esxi is plugged in: Sophos XG is unreachable of course. Esxi is now accessible from my workstation with no packet drops. Esxi can also now ping everything on the network and can now traceroute.
Before Sophos XG everything was working perfectly. I was using Sophos utm and has no issues on the network. I can even think about would could be causing this weird issues
Things I have tried:
Change the whole subnet, once esxi and Sophos where back on same network things broke again.
Changed the IP.of Sophos XG and of esxi to see if maybe there was something interfering. This did nothing
