What version of FreeBSD?  That command did not work on my 11.1-RELEASE-p6
system.


root@apron:~ # route add -net 1.2.3.4 gw 127.0.0.1
route: bad address: gw


Here's what worked for me.  Just use route del with the same parameters


root@apron:~ # route add -net 1.2.3.4 127.0.0.1
add net 1.2.3.4: gateway 127.0.0.1
root@apron:~ # netstat -nr
