How to Restrict Admin Panel Access by IP Address

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
