Custom rules do not apply (ip whitelist with custom rules)

[pierrecorsini]

Hello

Context

I'd like to accept incomming data from a single IP using custom rules.

Scenario

• Add the following IP Rules (replace with real IP) -A INPUT -p tcp -s x.y.z.a -j ACCEPT
• Apply rules
• Check iptables and try to acces the host with the previous IP
• ❌The IP is not present in iptables rules and I am not able to access the host with this IP
• Remove the custom rule and add the whitelist IP using the Whitelist menu.
• ✔The IP is visible in iptables rules and I AM able to access the host with this IP

Could you please advice ? Am I doing something wrong or is there a code-issue ?

Best regards

Support, it really doesn't work well. I managed to add only one simple rule which is given as an example.
