[SOLVED] I don't know what the correct command is for this on FreeBSD ?

[SakakiKomachi]

What command is used to make only IP 192.168.1.1 only access SSH?

Going out of my "comfort zone" (full disclosure)....

More information needed;

Are you trying to configure a specific default router or simply force the use of SSH?

Perhaps this link:

https://bobcares.com/blog/set-static-ip-and-hostname-in-freebsd-12/

See the paragraph:

"Set Static IP Address on FreeBSD 12"

Or (force SSH):
