Why not do this one step at a time, and get bridging working first?
- /etc/sysconfig/network-scripts/ifcfg-br0:
DEVICE=br0 TYPE=Bridge BOOTPROTO=dhcp ONBOOT=yes
Looks ok.
- /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0 TYPE=Ethernet BOOTPROTO=static BROADCAST=192.168.255.255 IPADDR=192.168.255.10 NETMASK=255.255.255.0 NETWORK=192.168.255.0 GATEWAY=192.168.255.10 IPV6ADDR= IPV6PREFIX= ONBOOT=yes USERCTL=yes IPV6INIT=no PEERDNS=no BRIDGE=br0
Do you want me to remove the "BRIDGE=br0" from "ifcfg-eth0"?
But this doesn't. An ethernet bridge ties together multiple ethernets to give the "illusion" that it is one ethernet. An interface that is added to the bridge is just a bridge port. The configuration for the NIC should simply add it to the bridge, e.g.:
DEVICE=eth0 TYPE=ETHER BRIDGE=br0 ONBOOT=yes
The resulting bridge device (br0) is the interface to the new ethernet. So, if you want to give it a static IP address, do it in the bridge configuration. A quick example:
/etc/sysconfig/ifcfg-br0:
DEVICE=br0 TYPE=Bridge BOOTPROTO=static BROADCAST=192.168.255.255 IPADDR=192.168.255.10 NETMASK=255.255.255.0 NETWORK=192.168.255.0 ONBOOT=yes USERCTL=yes IPV6INIT=no PEERDNS=no ONBOOT=yes
The static address is the same as my ifcfg-eth0's static address. Is this on purpose?
Once that works, continue with the other stuff :).
