• Hi, I have solved the issue by changing the PVID on this trunk port back to be VLAN 1. I guess as having it as 99 both the untagged and the true management VLAN were both being tagged as 99 and the untagged DHCP server was winning. Thanks
  • Hi, what I forgot to add was that DHCP is handled by my router (pfsense). The switch is connected to the router via a trunk port. All VLANs are allowed on the port, and the PVID is set to 99. The port is also flagged as uplink, I presume as that is the route to the internet for the switch.
