I think I need a fresh set of eyes for this one…
I have two switches. One is Cisco the other Ubiquiti. I have 4x 1 Gbit ports aggregated between both switches and on the Cisco switch, all those ports are set to TRUNK mode.
I recently changed one of the wireless networks (the APs connect to the Ubiquiti switch) from the default VLAN to VLAN 30. The clients connect but are unable to obtain an IP address from the DHCP server (pfSense).
The firewall logs no blocked packets, nothing. I can only assume that the VLAN traffic isn’t getting through over the interconnecting switch trunk. Default VLAN traffic is getting through but not anything else.
I have also added a new “Network” in the UBNT side of things to match, but I still can’t work out what I’m doing wrong.
