I’m creating a firewall HA cluster. The proof of concept for the basic firewall cluster is OK. I can bring up the cluster, start the iptables firewall, and move all of this with no problem. I’m using Conga to do all of this configuration on CentOS 6.3 servers.
To extend the “HA” part of this, I’d like to use bonded channels instead of plain old NICs. The firewall uses the “IP address” service for the outside firewall IP addresses. Each server behind the firewall is NATted to one of these external IPs on the firewall’s external interface.
I’m not seeing how I can use bonded channels anywhere for these “IP
address” services. Part of the problem is that Conga will “guess” at which interface to place the ip address service upon. In the case of bonded channels, I don’t think Conga is even aware of the “bondx”
interface, and Conga only uses interfaces like eth0, eth1, etc.
I realize that the sysconfig network scripts will come into play here as well, but that’s another problem for me to tackle.
Does anyone have any experience with bonded channels and Conga? I could sure use some help with this.
