For reference: As far as I know, bridged networking is only really documented for virtualization, but this link covers creation of a bridge and adding a single interface to it, and disabling iptables for bridges: http://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/5/html/Virtualization/sect-Virtualization-Network_Configuration-Bridged_networking_with_libvirt.html You'd simply set up both eth2 and eth3 as eth0 is set up in that example. The options available in ifcfg files are documented in: /usr/share/doc/initscripts-*/sysconfig.txt
