To make network settings on FreeBSD first we have to check the name of interface using following command:
$ifconfig
emo: flags=8843 metric 0 mtu 1500
options=9b
ether 08:00:27:11:11:78
media: Ethernet autoselect (1000baseTX)
status: active
1oo: flags=8049 metric 0 mtu 16384
inet6 fe80: : 1%100 prefixlen 64 scopeid 0x2
inet 12.0.0.1 netmask 0xff000000
Now enter these command on prompt using network card name (emo).
$ ifcnfig em0 inet 192.168.1.54 netmask 255.255.255.0
$ route add default 192.168.1.1 gw
$ vi /etc/resolve.conf
write in the file
nameserver 192.168.1.1
nameserver 192.168.1.2
