[Pacemaker] New to Pacemaker - Firewall Question

[Jake Bogie]

Hey All,

 

I'm trying to learn some more about Clusters for some research I'm
doing. First thing I need to say is this project is absolutely
AWESOME!!!

 

I've installed and enabled the Pacemaker system and I have it running.

 

The issue I am dealing with is that whenever IPTABLES is enabled the
cluster nodes cannot see one another. If I flush all of the rules from
IPTABLES the nodes talk to one another perfectly fine.

 

I have two ring interfaces:

 

        interface {

                ringnumber: 0

 

bindnetaddr:172.16.103.0

mcastaddr:224.1.0.1

mcastport:4000

        }

        interface {

                ringnumber: 1

 

bindnetaddr:172.16.104.0

mcastaddr:224.2.0.1

mcastport:4000

        }

 

And I added the following rules to IPTABLES:

 

-A RH-Firewall-1-INPUT -p udp -d 224.1.0.1 -j ACCEPT

-A RH-Firewall-1-INPUT -p udp -d 224.2.0.1 -j ACCEPT

#-A RH-Firewall-1-INPUT -p udp --dport 4000 -d 224.1.0.1 -j ACCEPT

#-A RH-Firewall-1-INPUT -p udp --dport 4000 -d 224.2.0.1 -j ACCEPT

 

The two commented out rules didn't work so I tried the two above.

 

What am I missing here?

 

Thanks,

 

Jake
