Hi, Perhaps it was originally setup as a second wan port. Make sure it doesn't have a dhcp client (or pppoe client) or static address attached to it. Is it listed as wan in interfaces/Interface list Regards Roger

No DHCP client, no PPPoE client, not listed as a WAN interface, does not have a static address attached to it. Regards, K.

Hi,
I'm a bit mystified as to why it would have been configured like that. I regularly use ether1 as a WAN and disable ether2, as I might want to use it as another WAN port later. Keeps things neat and tidy.

Hi,
can I just enable the port in the bridge As long as it is not part of some other configuration, then yes.

Of course! : ) Just watch out for some scripted or automated task that might be configured to disable again under some conditions... e.g. check system->scripts and system->schedule and tools->netwatch in particular. Since you say that you didn't do the original config yourself, there's no guessing why anyone would set it like that - other than did it 'temporarily' for some reason (like to access the router admin interface without putting the connected device on the LAN) and then forgot to 'undo' it ; ) Cheers! Mike. the
port in the bridge?

I always keep copies of all devices configs (from a /export) in a folder on my laptop and in a private Internal git server. Then, as a Unix guy originally, I’d just run a “grep ether2 config.rsc” and see if it’s listed anywhere else. If so then dig into the .rsc file and find out what it is. If you are trying to find some random script or bit of config through Winbox or Webfig you are way too likely to miss things. Even if it’s one of your own devices that you are familiar with. Cheers, Andrew
