Re: commonly blocked ISP ports

  • From: Peter Dambier

There is only one port worth blocking:

Block port 80 (http)

All other ports might be in use for redirected ssh, telnet, ftp, ...

Blocking port 80 will keep windows people from accidently clicking nonsense.

:)

Kind regards,

Everyone,

Does anyone have a reference point for commonly blocked ports?

We have a list, some reactive and some proactive, however we need to remove ports that are no longer a threat and add new ones as they are published.

Thanks
