Windows 7: Firewall question...

Firewall question...

I've tried two free firewalls for Windows7. Windows7 Firewall Control and Privatefirewall 6.1. When I do a Shields up scan with Gibson (www.grc.com), both of these report that port 23 (telnet) is open. Is this normal? I have'nt used it for a long time, but if I remember correctly, when I used Zone Alarm pro with XP, GRC would report true stealth on all ports.

can you explain your problem with some more details and may i know the reason for using such external firewalls while 7's FW is quite strong n AVG's is the best i think.

I believe port 23 is for telnet.

Edit..

Google just confirmed that port 23 is for telnet. So no worries there for you

Telnet should definately not be open. its one of the easiest way to gain access to a remote computer. All you have to do is type "helo" and it will tell you abt the system.

ZAP, ESET, both stealth all ports on GRC. You have a realtime virus checker runnning?

I thought 7's FW was quite adequate as well. I use Windows7 Firewall control along with 7's FW as its built to be compatible and eases the set up of the 7 FW. But I was VERY surprised to see GRC say that port 23 was open even with the 7 FW running. I don't think that's good. I may go back and try ZA free since the newest version seems to indicate that it plays nicely with Windows 7.

I agree with Ken on this one... its like hanging a neon sign on your front door.. "Not home .. Come on in" I use MSE and score a True Stealth on GRC.com btw..

No reason to have it open. Its not even included in the OS anymore. telnet is a bi-directional com that is easily hackable. Google it and hacking and you'll you see. We make sure FTP is closed, and you wouldn't think of leaving remote desktop without a password so too with telnet.

Hi Ken!

I'm using MSE currently (although there is a new beta version of AVAST 5 that has come out that looks like it fixes alot of problems with the first beta that I might try). I was toying with giving Norton Internet Secuity 9 a go (something I didn't think you'd ever see me say after all the days of Symantec "bloatware") but they want $60 for it and I HATE having to pay for a AV/FW YEARLY! May give ZA free a go.

If you want to have real protection(firewall in this case) you need to use a paid software, not the free ones or worse Windows firewall.
