If you have Optigo's PC-based capture tool software installed on a Red Hat Enterprise Linux or CentOS Linux system, and you want to be able to access the capture tool's management interface via Chrome from a different computer on the same LAN (Local Area Network), you need to make sure port 4000 is open.
To do so, open up a terminal on the capture tool's host machine and execute the following commands:
firewall-cmd --zone=public --permanent --add-port 4000/tcp
Then, try accessing the capture tool from another computer on the LAN.
