Banana Pi R4 how to change WAN port to LAN

[MrPLC]

Hi guys,
I am a noob here with OpenWrt, I bought a Banana Pi R4 with SFP ports and added a wired SFP 10Gb for my Main Wan port, and it is working great, my ISP speeds bumped like 30% or more from my R7800 DDWRT, so happy with the upgrade, but I will like to use the wired 1Gb mark as WAN to an additional LAN port, my old R7800 had 4 ports and I was using all of them and I don't have space to put another switch.

typically it is as simple as removing the port from the wan network interface (or from br-wan) and adding it to br-lan.

To be sure we can guide you to do the right change, let's see the config:

Please connect to your OpenWrt device using ssh and copy the output of the following commands and post it here using the "Preformatted text </> " button:

Thanks in advance

So assuming you're using the sfp wan port currently, just remove the regular wan port (last line) from br-wan:

@MrPLC

config device
        option name 'br-wan'
        option type 'bridge'
        list ports 'sfp-wan'
        list ports 'wan'

Then add it to br-lan like this:

config device
        option name 'br-lan'
        option type 'bridge'
        list ports 'lan1'
        list ports 'lan2'
        list ports 'lan3'
        list ports 'sfp-lan'
        list ports 'wan'
        option ipv6 '0'

Restart and test. It should work.

Thanks @psherman it worked like a charm.
