I have another problem which I realized just now.
I configured via rc.conf the ip and netmask below but when I do ifconfig 
the netmask appears as /24

calamardo# cat /etc/rc.conf | grep ifconfig
ifconfig_nfe0="192.168.10.9 255.255.0.0"
calamardo# ifconfig nfe0
nfe0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
        options=8<VLAN_MTU>
        ether 00:1d:60:7e:38:7e
        inet 192.168.10.9 netmask 0xffffff00 broadcast 255.255.0.0
        media: Ethernet autoselect (100baseTX <full-duplex>)
        status: active

This makes impossible to use 192.168.30.100 and 192.168.30.1 since they 
are on different networks and are unreachable (according to ifconfig).
