    Default Device in ARP table but not in

    Hi all, hoping you can help!

    I have two Cisco APs, one appears in the host/devices list, the other doesn't but it is listed in the ARP table of the internal interface.

    Any ideas how I can fix this and get the second AP to appear in the host/devices list?

    Thanks

    Phil

    If the device does not have traffic crossing the Untangle, then it will not be listed in the host table.

    But yet, if it's not crossing the gateway, how is it in the ARP table... I mean it's clearly possible, but it seems rather odd that a device would bother to communicate with the gateway, but only on layer 2?

    dhcp, communication with untangle itself, etc.

    Duh, It's a WAP right? Which means anything beyond the WAP would force Untangle's ARP table to know what it is, as it passes the frames to Untangle for those other devices. But if the WAP itself doesn't go to the Internet for anything... not in the device list.

    So now my question is, how did the OP manage to configure two presumably identical WAPs to behave differently.

    Maybe one is auto checking for updates and the other not?
