Only because my client doesn't have a static IP address and i don t want
to open ports for everybody ...
Am i wrong to try that ?
Yes. Why don't you match on MAC address instead?

I suppose that you want to open ports from the net side of your fw.

In similar cases that I encountered ipsets + some scripting solved the problem.
Since you know your clients host name "foo.no-ip.org" or whatever

a dig or host or nslookup will tell you the IP address that you can then insert into your ipsets

make this a daemon that wakes up every x minutes.

make sure you flush your particular set before you update to delete garbage ips.

So shorewall + ipsets is the thing you have to study now :-)
