After setting up VLANs successfully, a new one will not work.
I might be losing my mind. I'm a new pfsense user, and after successfully setting up 3 VLANs last week, I went to set up a fourth and cannot for the life of me get it to work. I am using a Unifi EdgeSwitch10x and Unifi AP Pro. I believe I have narrowed the issue down to my pfsense configuration, but after comparing everything from a working VLAN to the new one, I cannot find a configuration issue. I intended to use VLAN4 on the AP, but to troubleshoot I have plugged a laptop directly into the switch. If I set the switch to untagged VLAN3 only, it works just fine. Changing it to VLAN4, I get nothing. No LAN access. When I tried through the AP, it was reporting a DHCP timeout. I believe all relevant settings are pictured below, so perhaps I am missing a step in the process? I've gone through several step by step guides and don't believe I'm missing anything, but that is probably the case. For the sake of troubleshooting, I have added a firewall rule to allow all traffic on VLAN4. If anyone has any ideas, I would be grateful.
Sounds like you haven't tagged VLAN 40 on the switch port connected to igb1.
Thank you so much. I just knew I was missing something stupid. I'm brand new to all of this. Couldn't for the life of me figure it out. Spent a couple hours going over settings before posting this. Thanks a bunch.
