Does the GL-MT300N-V2 have a firewall and if so, how do I configure it to open certain ports, if not, why not, and how to add a firewall and which firewall to add?
Solved. Of course, this excellent mini router has a firewall that is enabled by default and much more, but you have to use the “Advanced” Router’s Menu, the Admin Menu accessible from the “Advanced Settings” in the upper right of the regular menu, or from the link below.
