This is probably a super easy question but I can't find the answer online. I have an actiontec router, and when I'm under "Add Port Forwarding Rule", I have one checkbox that says "Specify Public IP Address". If I check this box, I'm given an option to include a Public IP Address.
What does this address mean? If I check the box and add an address say (55.555.555.555) for example, then will this rule only be applied when the incoming computer's address has an ip of 55.555.555.555?
