Anyone got OPNSense to use a TailScale Exit node elsewhere instead of its "wan"?

Hi all,

I incorrectly posted this in 25.1 section and so am hoping someone might see it here who can assist.

I can configure OPNSense for Tailscale using the new plug and is working as expected.
Ether configured as an exit node or to expose whatever is behind it via subnet router option works etc etc.

Massive shout out to Sheridan Computers for writing the plugin too.
https://www.youtube.com/watch?v=VD2oMin_V3M is what I followed along to.

I have a linode linux VPS box already configured as a TS exit point which has been working nicely for a while now, but only being used by a single client behind the OPNSense router.
I would like to "transfer" from a single client using the exit point to my OPNSense router to use the Linode/Tailscale exit point.

So, I don't think the plugin is mature enough for this, but am curious if anyone has done this prior to the plugin release via the command line and are willing to share their success?

There's chatter around having two wan connections:

or

modifying outbound NAT with the additional of FW rules
https://forum.opnsense.org/index.php?topic=45530.msg227721#msg227721

but both haven't succeeded.

And so am wondering if anyone has successfully done this and are willing to share.
