Bandwidth limit on natted connections

Hi, i’ve a WebDAV server (https), and i connect to it from external ip (other home, work, mobile phones etc).
I want to limit bandwidth of any ip that connect to it.
In NAT rule there is “connection-limit” option, is this for my problem?
How can i do to limit this connections?
Obviously, i don’t know external ip of everyone, they are all dynamics.
If could help, i can setup many NAT rules with different triggered port, and then every “user” uses different port to access the same server.
Thank you very much!

Thanks for “answer”.
I already use simple queues, but in this case i’m not able to implement its.
I’ve not an IP, all external IP are dynamics, only i can “use” port triggering or a protocol (davs) to identify a connection… But I don’t know how to use it in a rule!
