Hello,
while testing devices on virtual machines, I noticed some ports needed to allow tango to run.
Those ports does not seem to be documented for now, I think this could help so I put this here to confirm (I think it then it should be entered in documentation, place to be defined).

1. since TANGO_HOST is associated to an IP and a TCP port (often 10000 or 20000), communication to this server should of course be allowed on TCP port.

2. communication on 20001 TCP port is mandatory for a server running tango-starter service.

3. I remember that those ports are choosen randomly on a given range by default. Since I see on jive the port associated to a device, which is often greater than 20001, I understand TCP communications on port greater than 20002 (from 20002 to 65535?) should be allowed if at least a device runs on the server.

Do you confirm those informations?
Are there some other port ranges to know, especially for IT teams?

Regards
