Automatically enable and disable a router's DMZ
Why not open the ports you need instead of activating the DMZ? Putting any machine except a stripped server in a DMZ is dangerous.
Agree
I can only agree. If you're not sure what ports are active or used because the documentation is poor (like pcAnywhere), you can briefly set up your computer as a DMZ address. Then connect using whatever program/service of interest, like Acquisition or BitTorrent, and run "netstat -a" in a terminal session. Note which ports are active and whether thay are TCP or UDP. Then, take the computer out of the DMZ and open the appropriate ports.
Agree
Or install somthing like Little Snitch, which will alert you when an application is trying to connect over a non-standard port.
Also agree
I also agree. Open ports on the router selectively (which is a capability of three different brands of consumer-grade routers I've used -- Linksys, D-Link, Belkin). Don't expose the entire system.
Agree also
DMZ's are dangerous for security. |
