Restrict OpenAdmin

To restrict OpenAdmin access only to your team, whitelist your server's IP addresses on the firewall, and then disable port 2087.

Whitelist your team's IP addresses​

Replace YOUR_TEAM_IP with your actual IP addresses. Repeat for each team IP.

csf -a YOUR_TEAM_IP

Block all other access to port 2087​

Edit /etc/csf/csf.conf and remove 2087 from the allowed TCP_IN list, or run:

csf -d 0.0.0.0/0 2087

Then restart CSF:

csf -r
