How to setup firewall FreeBSD?

Hy ! My server is until FLOODing by someone.
Him is attacking port 3306 [ i tried to change it but site can't connect with new port and i added IP:newport].
I have ipfw.rules but can't stop it.
Any idea?

well 3306 is your MySQL Port, you can change that one...

You can block port 3306 (mysql) for everyone, except your Homepage and your Pc/Ip.

I tried to allow IPFW only for my IP and host IP but can't connect website with port of ping [Only registered and activated users can see links. Click Here To Register...] [my website]
Any ideas?

Don't know... Better ask in a FreeBsd forum. They know more about freebsd firewalls.

Set a second IP for your mysql port and block this port for any user let the homepage coneckt to 3306 on the new ip and your problems its going away !!!!!

set up a packetfilter, which block every port which shouldn't be opend, like mysql, p2p and database port's. also set up rules for filtering incoming traffic and attacks like this nooblike flood will be blocked automatically

can you give me a packetfilter config? I am noob :(
