Oops : I forgot to give you the config !!

I'm using aMule 1.2.6 on a Gentoo w/ AMD XP1800+/nForce2/3Com Onboard NIC/Gnome 2.6/Giptables 1.1

It's a bit hard to tell from your description, but as far as I can see, the 200 ports you are reffering to are the outgoing connections, and you shouldn't have to open your firewall for those.

Try executing this command while aMule is running. It'll show you the 3(!) ports you need to open in your firewall: 'netstat -npl | grep amule'

Cheers,
Xaignar

Well... first of all : thx for your answer ;)

Here is the result :
$ netstat -npl | grep amule
(Tous les processus ne peuvent être identifiés, les infos sur les processus
non possédés ne seront pas affichées, vous devez être root pour les voir toutes.)
tcp 0 0 0.0.0.0:4712 0.0.0.0:* LISTEN 9986/amule
tcp 0 0 0.0.0.0:24662 0.0.0.0:* LISTEN 9986/amule
udp 0 0 0.0.0.0:24665 0.0.0.0:* 9986/amule

unix 2 [ ACC ] STREAM LISTENING 188703 9986/amule /home/logon/.aMule/muleconn

But : all those ports are opened !

And if I run snort (firewall shuted down) I've got :
05/28-20:01:28.357483 xxx.xxx.xxx.xxx:50287 -> yyy.yyy.yyy.yyy:5662

Those are outgoing connections to other *Mules for data transfer. You tcp/udp port are used for incoming, and the kernel is the one deciding which ports to use when we open it with no port number. It's more a wxWidgets issue (we use wxSocket) than our own.
