OpenVPN - Bridging Mode

Scope:  OpenVPN 2.2.0 on CentOS 5.6

Previously I documented the install of OpenVPN on Debian in a bridged configuration.  Later I installed a similar setup on CentOS 5.6 and found that some additional steps were required.

 

As a place holder and reminder....

 

Create ifcfg-br0 file.

 

cat /etc/sysconfig/network-scripts/ifcfg-br0

DEVICE=br0
TYPE=Bridge
IPADDR=192.168.0.100
NETMASK=255.255.255.0
GATEWAY=192.168.0.1
ONBOOT=yes

 

Modify the ifcfg-eth0 file (or the interface file you are creating the bridge to)

 

cat /etc/sysconfig/network-scripts/ifcfg-eth0

 

DEVICE=eth0
TYPE=ETHER
BRIDGE=br0
ONBOOT=yes
 

Set Scripts to run at start-up.
