Unable to get agent to connect to server

[usao]

I have a CentOS 6 environment. Installed a Zabbix server and installed the agents on the Guest OS (also CentOS 6) using the following commands:

rpm -Uvh http://repo.zabbix.com/zabbix/2.4/rh...el6.noarch.rpm
yum install -y zabbix zabbix-agent
chkconfig --levels 235 zabbix-agent on
vi /etc/zabbix/zabbix_agentd.conf
Server=<Zabbix IP>
Hostname=<hostname>
service zabbix-agent start

Added the following to /etc/sysconfig/iptables:
-A INPUT -s <Zabbix IP> -p tcp --dport 10050 -j ACCEPT

However, I appear to be getting errors in the audit.log file indicating:

type=AVC msg=audit(1421932447.249:156818): avc: denied { write } for pid=15791 comm="zabbix_agentd"

I tried to make selinux permissive, but that didn't help.
