Hi all. I'll try to explain this as best I can.
We have a new building next door that is connected to the main building via fiber. We needed to be able to segregate this building so I assigned it its own VLAN. We use Sonicwall for our router/firewall and I set up a sub-interface for the new VLAN on 3 interfaces (LAN, WLAN, and VOIP) and tagged the appropriate ports on the switches to allow traffic from the new VLAN as the new building piggybacks off of our core switches. I got the LAN and VOIP working fine, and the WLAN works when plugged into the switch directly and even the UniFi APs were able to pull DHCP addresses. However, now when I try to join the WiFi at the new building it fails. When I tested it with my phone it hung at obtaining IP address. Setting a static address doesn't work either. I ran a packet capture on the sonicwall and it is receiving the request and issuing a response, so I don't think the issue is there. I'm almost 100% certain the issue lies in the UniFi APs. Does anyone have any experience with these on a VLAN? We use them at all our other sites but there is no VLANing besides in this building so that could be a reason.
