I'm just wondering why you need it for incoming port attacks on the WAN when it can't be accessed from a local NIC that isn't addressable.
Now, if it's a server that's on the net, it's a nice trick. What I do is the simple thing. I turn off pinging and change the ports and have strong usernames and passwords.
My question on the port knocking is what firewall and software on your client is required to make it work. I wouldn't want to have to knock putty 5 times manually with the right timing to connect with ssh.
