IP is for the client does not have access

It should already work. Just define access entries per IP address/network and then you may enter the connection limit per IP. Don't forget to remove the wildcat (*) entry.

In what version is available?. I use TVH V 3.9. Can you give me an example of how to limit by IP. can i use username, password and ip to limit connection.

This is in case of lots of clients have de same user and pass
