________________________________________
00100 allow ip from any to any via lo0
00200 deny ip from any to 127.0.0.0/8
00220 divert 8668 ip from any to any via ed0
00400 deny ip from 127.0.0.0/8 to any
00615 allow tcp from any to MY_IP 22,5617,10000

I have done the first part -> opend the port required for FTP (only a
different port than normal)

00625 allow tcp from MY_IP to any
00650 allow udp from any to MY_IP
00700 allow udp from MY_IP to any

As far as I know, these lines make it possible for my server to connect to
everyone on every port.

00750 allow icmp from MY_IP to any
00800 allow icmp from any to MY_IP
00850 allow ip from 192.168.0.0/16 to any
00900 allow ip from any to 192.168.0.0/16
65535 deny ip from any to any
