"Custom" Firewall Setting (AMG1302-T11C)


I have the AMG1302-T11C router. I've been able to set up port forwarding successfully.

In order to do that I had to change the General Firewall settings from the default value of "Medium" to "Custom" (see attached screen shots from the manual).

Is it correct to assume that "Custom" has the same level of security as "Medium" except for allowing individual firewall rules to be set? i.e If I don't set any individual firewall rules does selecting "Medium" mean the same as selecting "Custom"?

The reason I ask is that I want to be confident that no other security settings have been relaxed by selecting "Custom".

Many thanks!
