I have a pfSense firewall serving some Unifi switches and Access Points.
I have been doing some experiments in order to move the infrastructure to a dedicated Management VLAN (relatively easy), while also allowing adoption of new Unifi equipment to function (harder) and minimise use of the default VLAN 1 (common security advice, seems pretty difficult to actually achieve).
As part of this , I have been trying to put the main LAN (created with the WAN during installation) on a VLAN. This seems to be impossible. I have other VLANs working fine, but connectivity is lost immediately I do this , even with port settings at ALL. Switch the LAN back to a basic interface and the connection returns ??
