Question about router

[Hairboi]

Is there a way to cut off the internet to a certain ethernet port on the router, whilst keeping it going on other ports?

It says it's a Linksys AG241V2.

I am unable to physically get to the router at the moment, and need to disable it going through one of the ports.

Check if it supports port-based VLANs. If so then it should be possible to achieve what you want.

If you cant do port based VLAN's, cant you setup a firewall rule up to block certain traffic for a specific IP address?
