Setting up two IP address on single NIC
There are some times we require two IP address to set up so that we can make a Linux box as a router. It can be possible without even having two NIC cards. We can configure more than two different IP address on single Network Card as shown below:
This example is on Ethernet.
STEP 1: Setting up first IP address. Edit /etc/sysconfig/network-scripts/ifcfg-eth0 on Red-hat Linux box and give the following entries as shown.
vi /etc/sysconfig/network-scripts/ifcfg-eth0
- DEVICE=eth0
- BOOTPROTO=static
- IPADDR=192.168.1.10
- NETMASK=255.255.255.0
- NETWORK=192.168.1.0
- ONBOOT=yes
