Basicly that means you need to setup up your box to forward packets:
https://www.freebsd.org/doc/handbook/network-routing.html#network-dedicated-router

Getting the routing working is a little bit more difficult but the
handbook has useful instructions:
https://www.freebsd.org/doc/handbook/network-routing.html

You can use a routing daemon to advertise routes, but not all devices
default to listening to routing advertisements and may need to be enabled...

FreeBSD includes routed(8) that provides basic functionality...
