SG-1000 - Devices on Untagged LAN interface not reachable

  • Hi All,

    I have an SG-1000 that has been working fine for a couple of years. I recently needed to add a new VLAN to the Lan interface (KWIFI (opt2) -> cpsw1.40) and since than I can connect to anything on the untagged VLAN ( LAN (lan) -> cpsw1 )

    *** Welcome to pfSense 2.4.2-RELEASE-p1 (arm) on edge ***
     WAN (wan)       -> cpsw0      -> v4:
     LAN (lan)       -> cpsw1      -> v4:
     SWIFI (opt1)    -> cpsw1.30   -> v4:
     KWIFI (opt2)    -> cpsw1.40   -> v4:

    The SG-1000 LAN is connected to a Unifi Switch trunk port. The Unifi Switch has a number of Unifi AP's connected to it. Traffic appears to be working from the APs correctly on the VLAN interfaces. However, I can't connect to anything on

    I tried to post more detail but was getting blocked by the spam thing.

    That all looks correct and I just tested it and it worked fine. I would double check the switch is configured for untagged + tagged 30, 40 on that port.

  • I have resolved the issues by rebooting the SG1000. I can now ping and connect to devices in the Untagged VLAN.
