IPTABLES and HEARTBEAT/DRBD

[jfer]

How can I setup iptables/shorewall on 2 NICs running DRBD and Heartbeat.

I have followed Perfect Setup for NFS High Availabilty Server and added
a second NIC (eth1) just for Heartbeat Broadcast and DRBD synchronization.


PC A:
eth0 = 192.168.0.2
eth1 = 192.168.1.22

PC B:
eth0 = 192.168.0.3
eth1 = 192.168.1.33

eth0:0 = 192.168.0.4 (virtual interface for heartbeat)

eth1 on PC A and PC B are connected thru Gigabit switch just for DRBD Sync and Heartbeat Broadcast..

eth0 on PC A and PC B are connected to my LAN switch.

Resources are accessed on eth0:0 (e.g NFS and SSH
