[ossec-list] What tcp and udp ports must be open between the agent and the server

[Peter M. Abraham]

Greetings:

Since upgrading to ossec 1.5 we have several agent servers that can no
longer communicate with the ossec control server.

If iptables on the agent servers is off, communication works.

Turning on ipables on the agents, communication fails.

In the past, just having UDP 1514 open to/from the ossec control
server was enough.

Are there any other ports, including any ephemeral ones that need to
be open?

Thank you.
