Disable the interface address assigned by dhcp

Hi, I have a question to ask. How can I disable the dhcp server from assigning IPs to the ether1 interface?

Depends on the context of the question …

ether1 interface itself (don’t put a dhcp client on ether1) or devices connecting through ether1 ? (firewall rule to block UDP/67-68 ports coming/going to ether1, I would think).

Can you explain a bit more why you want to block DHCP requests on 1 specific interface of your router ?

The ether1 interface is the interface I use to bridge pppoe dialup with my carrier’s optical cat, and it’s currently assigned the IP 192.168.1.2, so I’d like to disable the dhcp IP assigned to it

I still don’t understand what you’re trying to do …

I want to disable the dhcp ip assigned to the uplink port of the ether1 interface

If you check

/ip/dhcp-client/

You should be able to see all DHCP clients running on your router, and then disable any instance you do not need.

An export of your config says more than thousand words:

/export file=anynameyoulike

Remove serial and any other private information like public IP.

And use code tags to make it readable.

Put a wad of gum over etherport1, solved.
OR
provide export of config so we can work from facts/evidence.
