As per the title really, I was reading that Tailscale sponsored a NAT Implementation in FreeBSD, which has made its way into pfSense - https://tailscale.com/blog/nat-traversal-improvements-pt-1#sponsoring-freebsds-endpoint-independent-nat-patch
This seems like a really useful compromise, which I imagine would be fairly popular.
For clarity I'm not seeking timelines or anything - I'm purely seeking clarity on whether its on the roadmap and/or whether any maintainers would be likely to be interested in implementing it in OPNsense?
