I understand you by previous message, so there is transcript of my
configuration (I have 172.22.2.0/24 segment attached with router
172.22.2.1 and my address 172.22.2.3)
Initial stage: I have directly routed subnet.
# netstat -rn

172.22.2.255 ff:ff:ff:ff:ff:ff UHLWb 2 163 fxp0
Now I am removing routing of subnet directly via interface:
# route delete 172.22.2.0/24
delete net 172.22.2.0
# netstat -rn

172.22.2.3 127.0.0.1 UGHS 0 1 lo0
Now I am adding routing for router address only (kernel need to know how
to reach router)
# route add 172.22.2.1/32 -iface fxp0 -cloning
add net 172.22.2.1: gateway fxp0

172.22.2.3 127.0.0.1 UGHS 0 1 lo0
So, there is only route for router and myself in routing table.
No I'll add route for all 172.22.2 network:
add net 172.22.2.0: gateway 172.22.2.1
