This is the iptables on my mysql_slave server:

# sample configuration for iptables service
# you can edit this manually or use system-config-firewall
# please do not ask us to add additional ports/services to this default configuration
*filter
:INPUT ACCEPT [0:0]
:FORWARD ACCEPT [0:0]
:OUTPUT ACCEPT [0:0]

It looks like you are missing a definition for the whitelist table. This should likely contain an accept rule for your primary server. I don't know if you would need to whitelist any other servers.
