DHCP only serves on port 1

Ok I am having issues with Sophos XG again (what a surprise) hopefully it's not just me being an idiot like last time, but pretty sure I have done it all right this time.

The issue is this, I have setup sfos on a physical machine instead of the virtualbox machine I was testing with, and I have 3 interfaces on the physical box, LAN, WAN and Guest (for just internet etc)  but the built in DHCP server is not having any of this, I have made a new DHCP policy and assigned it to my guest port (port 3) and here comes the fun but annoying part.

It is serving IP's from my new DHCP policy which I set to listen on port 3 to devices on port 1, totally ignoring the port1 DHCP server that's already setup :|

But it don't stop there, port 3 has no response from DHCP, If I manually set the IP then it works fine, so not a connectivity issue just DHCP server ignoring my settings.

The seems to be very little information on using more than just a LAN and WAN interface, I am still confused as to why my devices on port 1 are getting IP's from the port 3 DHCP policy and not the port 1 policy, how is this even possible???

  • Ok the issue was me being kinda an idiot again, the port 1 subnet was /16 which is why it worked when I changed port3 to 10.2.0.x

    Now got it working how I want after changing the subnet on port 1

    Hope my stupidity will help someone else on the forums :D
