SSH Port extern dedicated IP Adress

#1

Hello, folks,
I’m running on a V server on Internet UCS.
Which UCR variable must I set, that only a certain IP address externally (My Fixed IP) has access to the SSH port.

Thank you very much for your help

Hi,

I am unsure if sshd at all can block incoming requests based on IPs. I would try to user the firewall for this purpose.
Check developer reference, you can set filter rules based on ucr-variables. See here.
First I would create a rule with your IP and “allow” followed by a rule for all with policy “block” for all other addresses.

If you prefer to do with iptables, you can use .local files- see above mentioned doc.
