Hello,
Please note that Softether plugin reported:
os-softether-devel (misconfigured)
I would reach the local network from Windows Softether VPN Client. No chance.

Best regards.
Softether in FreeBSD quite limited when it codes to bridging.
Misconfigured is not a problem, you can resolve conflicts in System : Firmware
