Yes thats correct Sergio, our server is being hit hard, port scanned, brute force ssh and trying dns recursive exploit. For weeks.

I would like to know how to block all IP's from our ssh port, but allow a subnet or dyndns address that resolves.

Any help?

Hi,

Great product. We are experiencing attacks on our ssh port,we have changed the port but still continues.

Can you please explain how and what to enter to allow a subnet into ssh port and deny all others access to ssh port?

Very new to csf.

Thanks.
