You still haven't told us what is listening. No point connecting with telnet if that's not what is expected, but if on the server side you see the session ESTABLISHED, then the contact is there. You obviously know how to change the listening port, so what's it for?
In the target (192.168.0.179) , I am running a process called mgr which is part of an application called Golden Gate.
mgr process seems to have some issue holding on to this port.
I tried running another process (Oracle DB listener) on the same port 2012. This time the it hung for about 40 seconds and I got
Connection closed by foreign host error without hitting Ctrl+C
Code:
$ telnet 192.168.0.179 2012
Trying 192.168.0.179...
Connected to 192.168.0.179.
Escape character is '^]'. ----------------------> hung for about 40 seconds and then received the below error without the need for Ctrl+C
Connection to 192.168.0.179 closed by foreign host.
Both processes (mgr and lsnr) are run by the same OS user called oracle.

Since this is just a home based VM setup created for testing, I would like to disable all security/filter features in Solaris.
With the Oracle listener running configured for port 2012, can you open an ODBC connection? You might need to tweak tnsnames.ora on the client side to point to the correct port.
If that opens correctly (as a telnet would not handshake properly) then you have proved that this is not a network error (even if it's between to local VMs) and you need to be looking at the Golden Gate server to see if there is a configuration for that to allow certain connections, e.g. does it have an allowed IP address list, allowed users (e.g. does username/uid on client match username/uid on servers and is it allowed) It might depend how Golden Gate works.
Have you contacted the supplier? I can't find any matches after a quick web-search.
