Dave N asked:
I have seven IPs on my server. Using UFW, if I enter the rule ‘ufw allow 7443’, port 7443 is exposed and opened on all my IPs. But I only want port 7443 to be exposed on one particular IP address and to be closed on all the others. How do I achieve this?
Specify the destination IP address as the
sudo ufw allow to 198.51.100.205 port 7443/tcp
