3.3.3.3 = This is the virtual IP address you’ve been given.

[root@host network-scripts]# vi /etc/sysconfig/network-scripts/ifcfg-lo:0
DEVICE=lo:0
IPADDR=3.3.3.3
NETMASK=255.255.255.255
ONBOOT=yes
NAME=whatever
IPV6INIT=no
IPV6_AUTOCONF=no

Add an IP addressfor a VMWare machine (guest).

Make sure the the network interface for the guest machine is setup as “Custom” vmnet1 (this is host only).

host: 1.1.1.1
guest: 2.2.2.2

[root@host network-scripts]# vim /etc/rc.local

Add the following to the bottom of the file:

sleep 30
route add 1.1.1.1 dev vmnet1

Login to the guest machine and add the eth0 config.

[root@guest ~]# vim /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
BROADCAST=2.2.2.2
IPADDR=2.2.2.2
IPV6INIT=no
IPV6_AUTOCONF=no
NOZEROCONF=yes
NETMASK=255.255.255.255
NETWORK=2.2.2.2
ONBOOT=yes

Now create a route on the guest machine.

[root@guest ~]# cat /etc/sysconfig/network-scripts/route-eth0
ADDRESS0=1.1.1.1
NETMASK0=255.255.255.255
DEVICE0=eth0
ADDRESS1=0.0.0.0
NETMASK1=0
GATEWAY1=1.1.1.1

Finished.
