Ghostwall has open ports on 21-23 and others - HOW TO BLOCK?

Hi there.

I have a basic setup (default settings) + a few blocks on 123 and 135 (both work great).

But no matter how much I block ports 21-23, 1720 and other that are detected as "open" on grc.com (ShieldsUP) or PC flank test, they all remain this way - open!

So my question is:

How do I make blocks on port 21,22,23 so they are not "open" but closed or stealthed?

I will then use the same way for all other ports left "open" by GhostWall.

Thanks!

 

Hello there, LowWatermark.

Thanks for getting back on this issue.

You are correct. I am behind a router with NAT.

But blocking services on the router makes no difference on the grc.com ShieldsUP scanner service results.

I did, however, mange to close/stealth port 123 and port 135 using Ghostwall, with no modifications on router.

So it seems my router is penetrable, wheres as Ghostwall can/will block at least 123 and 135, but cannot/will not 21,22 or 23. At least not so far.

With your help, and any additional help available, I wish to close down these ports, as well as 1720 and a few others. So far, I have not succeeded.

But I see your point with the router being scanned rather than my laptop. That's why I am puzzled by being able to close 123 and 135 by Ghostwall.

Any further help, even on blocking by somehow getting my router to block as ordered, will be very much appreciated!

 

Services/processes using ports 123 (Time Service) and 135 (RPC's End Point Mapper) are from your PC, this is why GhostWall can block this traffic. Ports 21-23 are opened by router itself - GhostWall has no powers there and cannot block this. Log in your router and search for an option (possibly in advanced router settings) "FTP server". Turn it off, this will close/stealth ports 21-23.
