Flint 2 WAN port swap

Hi, I’m wondering if it is possible to reassign the “secondwan” interface to one of the 1gbe ports, from the default 2.5gbe (lan1)?

I have tried removing lan2 (1gbe port #1) from the br-lan group, assigning it as the interface for secondwan, adding lan1 to the br-lan group - it doesn’t appear to work.

For some reason the 2.5gbe WAN/LAN port remains tied to secondwan even after removing it as the associated interface device. If I make the above changes then plug the WAN cable back in to the 2.5gbe port, it immediately reverts back to the default of wan2.

Has anyone managed to get this to work?
