I haven't seen the OP describe traffic originating from ports 53036, 53037, 53038, 53039.
Geez Louise. Re-read the OPs post but concentrate on a single pair of ports:
- The server listens on 4 ports 8020 ....
- The client sends the first heartbeat from ports: 53036, ... to ports 8020, ..., This repeats in every 10 seconds.
- When server ... [it] replies from ports 8020, ... to ports 53036, ....
- If ... the server ... sends them to ports 53036, ....
Graphically:
step | Action | Server | direction | client
-----+--------+--------+-----------+-------
1 | Listen | 8020 | |
-----+--------+--------+-----------+-------
2 | h'beat | 8020 | <-------- | 53036 Client 53036 originates; S
+erver 8020 receives.
-----+--------+--------+-----------+-------
3 | resp | 8020 | --------> | 53036 Server 8020 originates; cl
+ient 53036 receives.
-----+--------+--------+-----------+-------
4 | data | 8020 | --------> | 53036 Server 8020 originates; cl
+ient 53036 receives.
-----+--------+--------+-----------+-------
4 ports at the server, 4 ports at the client; 4 bi-directional conversations. There is no ambiguity.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
