1. Host will be open on LAN and guests on WAN. Additionally, there is a bridged LAN for guests.
2. We will be using bridge networking for protecting the Host Network and saving IP addresses, also giving flexibility with the guest network setup.
3. Configure LAN Eth1 port to 192.168.1.2
4. WAN Eth0 port is not assigned any IP address.
6. Install the required bridge-utils package via:
yum install bridge-utils * Network:
# cat /etc/sysconfig/network
NETWORKING=yes
NETWORKING_IPV6=no
HOSTNAME=<host.domain.tld>
GATEWAY=192.168.1.1
GATEWAYDEV="eth1" * WAN Bridge device br0:
# cat /etc/sysconfig/network-scripts/ifcfg-br0
DEVICE=br0
BROADCAST=xxx.xxx.xxx.xxx
NETMASK=255.255.255.24
NETWORK=xxx.xxx.xxx.xxx
ONBOOT=yes
GATEWAY=xxx.xxx.xxx.xxx
TYPE=Bridge * WAN eth0 device:
# cat /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
HWADDR=00:30:48:65:12:b4

BRIDGE=br0 * LAN Bridge device br1:
# cat /etc/sysconfig/network-scripts/ifcfg-br1
DEVICE=br1
ONBOOT=yes
