Re: commonly blocked ISP ports

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
