You need to be using the SE Linux policy from the 5.3 update. Before 5.3, 
auditd never had a listening port and therefore selinux policy prior to it 
wouldn't have setup that type. I also think SE Linux policy may default to 
port 60 even though that port may not be guaranteed in the future.

Another thing that you should do on this is to setup the client's localport to 
bind to a port below 1024 and then set the server's tcp_client_ports to check 
that the ports are bound to that range as a security precaution.
