Those env var are used for RTIG listening port.
However they are NOT mandatory,
if you don't set the env vars default values are used:

  60400 for TCP
  60500 for UDP

Yes true, CERTI is not [yet] widespread enough to deserve a IANA
registration :=)
May be the time will come....

Moreover setting an "HLA services port" as a registered IANA port may
prevent from running 2 RTI on the same host which may be necessary
for building bridge.

I would say that teh baseline is:
 don't chose any and let CERTI use it's default value.

You may NEED to chose a port in the following cases:

  1) you need to run more than 1 RTIG on the same host
      because the host is shared by several user then you have
      to chose different PORT for each different user
      may be 60000 + uid would be ok for TCP
                  61000 + uid would be ok for UDP
      (depending on the span of the UID values)

  2) you need to reach RTIG behind a firewall
      then may be you have to choose the port negotiated with
      your security admin.

  3) ???
