Open port 4000 for Trader Workstation in Fedora
I have installed Trader WorkStation by Interactive Brokers. However, the program does not run, with assistance from support I found that the firewall is the problem.
The servers (several primary and backup servers) listen on port 4000 and 4001 (in case of SSL connection). The site recommends the following command for testing:
telnet zdc1.ibllc.com 4000
If I try to run that, I get
Trying 217.192.86.32...
telnet: connect to address 217.192.86.32: Connection timed out
I already tried to activate the port:
$ firewall-cmd --list-ports
1025-65535/udp 1025-65535/tcp
$ firewall-cmd --zone=public --add-port=4000/tcp --permanent
success
$ firewall-cmd --reload
success
The testing is still negative. Connection timed out.
How can I open the port? It would be ideal to restrict the access only to a few servers that are mentioned on the site. I have Fedora 27. Thank you.

I don't use Fedora, but according to the documentation:
List all open ports for a zone, for example dmz, by entering the
following command as root:
# firewall-cmd --zone=dmz --list-ports
To add a port to a zone, for example to allow TCP traffic to port 8080
to the dmz zone, enter the following command as root:
# firewall-cmd --zone=dmz --add-port=8080/tcp
To make this setting permanent, add the --permanent option and reload
the firewall. To add a range of ports to a zone, for example to allow
the ports from 5060 to 5061 to the public zone, enter the following
command as root:
# firewall-cmd --zone=public --add-port=5060-5061/udp
To make this setting permanent, add the --permanent option and
reload the firewall.
That should be a good first pass on getting IB to work. For what it's worth, this was the first search result for "fedora open ports".
