FreeBSD India

1) Use ifconfig command as follows:
ifconfig interface inet IP

Example(s):
ifconfig fxp0 inet 192.168.1.5

Note fxp0 is Ethernet interface name can be Obtained using ifconfig -a command.

2) To setup up ip permanently open file /etc/rc.conf ; add/modify network entries:
vi /etc/rc.conf

And setup values as follows:
hostname=”box1.freebsd.org.in”
ifconfig_fxp0=”inet 192.168.1.6 netmask 255.255.255.0″

Note ifconfig_fxp0 is Ethernet interface name can be Obtained using ifconfig -a command.

3) Again re-run /etc/netstart script.

FreeBSD allows you creat alias or assign multiple ip address to single NIC (network interface card)

My setup:
fxp0 - IP : 192.168.1.1/255.255.255.0
fxp0 alias - IP : 192.168.1.5/255.255.255.255

Note: Netmask must be diffrent otherwise you will get an error ifconfig: ioctl (SIOCAIFADDR): File exists

A) From command line use ifconfig command as follows:
# ifconfig fxp0 192.168.1.5 netmask 255.255.255.255 alias

B) You can setup this alias in /etc/rc.conf file by appending following text, so that next time FreeBSD comes up (after restart/shutdown) it will create alias for you:
ifconfig_fxp0_alias0=”192.168.1.5 netmask 255.255.255.255″

C)Restart FreeBSD network service using following script:
# /etc/netstart

D) Display alias and real ip using ifconfig lnc0 command:
# ifconfig fxp0
lnc0: flags=8843 mtu 1500
inet6 fe80::20c:29ff:fe01:ddbd%lnc0 prefixlen 64 scopeid 0×1
inet 192.168.1.2 netmask 0xffffff00 broadcast 192.168.1.255
inet 192.168.1.5 netmask 0xffff

Read ifconfig man page.

Setting up proxy on a FreeBSD server is very easy and helps to create a secure environment for your network, and also allows your whole network to access internet using a single internet connection.
Privoxy is a good proxy server. It’s very easy to use and worked well.

Installation
# cd /usr/ports/www/privoxy
# make install clean
# rehash

The configuration file is /usr/local/etc/privoxy/config, there is one line which must be changed:
listen-address 192.168.0.1:8119
The IP should be changed to your server’s internal LAN IP address. Also, it’s better to use a non-default port number for security reasons.
