Changing the IP address of a FreeBSD system is relatively easy and can be done with a few simple commands. The process involves using the ifconfig command pattern

Use ifconfig -a command to get names of Ethernet interfaces ifconfig -a Use ifconfig command to set temporary IP address (till rebooting system). ifconfig re0 inet 202.54.1.22 To

The private address space specified in RFC 1918 is defined by the following three address blocks: Range Number Network 10.0.0.0 – 10.255.255.255 16,777,216 10.0.0.0/8 (255.0.0.0) 24 bits 172.16.0.0

/sbin/ifconfig ppp1 down /sbin/ip link set ppp1 name my_ppp /sbin/ifconfig my_ppp up

In the kernel configuration add: options IPFIREWALL # firewall options IPFIREWALL_VERBOSE # enable logging to syslogd (8) options IPFIREWALL_DEFAULT_TO_ACCEPT # allow everything by default options IPDIVERT options IPFIREWALL_FORWARD

Building a gateway to the global network on FreeBSD – this is one of the most frequent cases using this system. The main pluses of this decision are:

The Combination of two 100 Mbit/c network cards into one virtual, with a 200 Mbit/s bandwidth. kldload /boot/kernel/ng_ether.ko kldload /boot/kernel/ng_one2many.ko ifconfig rl0 up ifconfig rl1 up ngctl mkpeer

How to add or remove alias for a network interface in FreeBSD Add: ifconfig fxp1 inet 192.168.2.1 netmask 255.255.255.255 alias Hide: ifconfig fxp1 inet 192.168.2.1 netmask 255.255.255.255 -alias
