Firewall Test your PC with free Port Scanner

Until now I fully relied on Gibson Research's online port scanning tool to check all of the firewalls's inbound abilities, which have at some point been installed on my computers ranging from checkpoint and to less known firewalls such as GhostWall. It might sound unnecessary to check firewall's inbound protection as we all assume it is basically powerful enough in most cases, but since my ISP supplied me with hardware firewall Vigor 2700 series with fully and (ir)reversibly opened port 80 and 8080, port scanning tool has become indispensable.

Using free Port Scanner from Auditmypc is not a difficult-to-use, fully automated online tool with basic and advanced scanning option with excellent reporting details, much better that the one found in Gibson's. This tool works fast and checks all of your computer's 65000 gates, each representing an online inbound and outbound communication path for every possible program ever designed.

Firewalls were built to close and mask these gates so non-allowed programs would never be able to use it and compromise computers. In reality most firewalls do the job very well but there are many least-known firewalls you should stay away from. So port scanning tools come here very handy to actually test if the firewall protects the way it should.

For my testing purpose I used Vigor 2700G hardware firewall from DrayTek, and after initial scan the results were worrying. Fully opened port 80 without ability to be closed and masked. I assumed it was defected router so I contacted my ISP which provided me with a brand new router of the same kind. Once again I ran Vigor 2700G through Auditmypc Port Scanner and results were the same. Port 80 and 8080 fully opened and exposed.


















This neat free online tool gave a valuable insight into insecurity of my computer so I can take necessary steps and appropriately protect myself from online threats.

ANSWER FROM DRAYTEK:

Port 80 and port 8080 are in certain scenarios used for remote purposes and firmware upgrade

PCTERRITORY REPLY:

Draytek provided us with additional information about this issue and explained that port 80 and 8080 actually does not pose a security risk but enables some ISPs to remotely upgrade firmware. Entire process is otherwise protected only certain IPs are allowed of such procedures so according to this explanation I can conclude that there should be no more worries about vulnerabilities for end-users who are using mentioned router Vigor 2700 series from DrayTek.
