Need Help with Corosync config

I'm setting up a two node corosync cluster using pcs (since crmsh is no longer supported) on CentOS 6.6

What I'm trying to do is have Corosync start iptables and bring up a secondary IP on an interface (needs to be a physical address as opposed to a floater, as IP tables is NAT'ing traffic to that address).

I'm lost at this point as almost every guide I find is on how to do so with crmsh.
