What is the simplest command line way of disabling and then reenabling the value `get_wanface`, in my case vlan2 ? Is it just an iptables command or is there something simpler ?
Thanks

I'm not sure what routers people are on here, but eth0 isn't used the same way in all routers. In the "modern" Marvell/Linksys WRT**** routers, which is my world here (unfortunately), eth0 is the WAN and eth1 covers the LAN ports.

To tweak Wildlion's suggestion just a bit, is this what you are looking for?

ip link set $(get_wanface) down
ip link set $(get_wanface) up

If that $( ) notation is new to you, try the commands with "echo" (and a space) out front just to see what they would do.

yeah I was being lazy

@ob2s

there are other ways like you said using an iptables command but it needs to be first to ensure that any other rules do not process

You could also just unplug the cable if it is in an easy location

You could set the default routes to be null

My original suggestion fit the term of "disable" and reenable the interface from the command line.

very cool, very simple, thanks
