How do I BLOCK ports in the firewall?

How do I BLOCK ports in the firewall?

Rather than opening up ports I need to block them... specifically 80 and 3306.  I am using a webserver (for localhost only for web dev testing purpose), but to make it a little more secure I would like to block all incoming from these two ports as well.

 

I know how to allow ports in the firewall, but how do you block them?

Re: How do I BLOCK ports in the firewall?

The firewall will block them if you are not making requests on them from your end or sending out requests to return on those ports.

 

Try Steve Gibson's Shields Up to check your ports, mine had Stealth on 1 thru 1056 and 3306 w/the RG firewall.

Re: How do I BLOCK ports in the firewall?

Thanks for the link - completely stealth. I would still like to know if it possible to manually and specifically block a port in the firewall though. I can only assume they treat the current firewall settings as a 'whitelist' due to the setup and options present. It would be nice to have the peace of mind that a specific filter has been added and blocked from your own rule.

The default on incoming ports is closed, with some exceptions for IPTV, VOIP and AT&T management of the firewall and other devices.  As such, it is not possible to close them explicitly.
