which ports to block ?

hi, i have written my own firewall script to protect my homelan using iptables. i drop all connections from the outside made to ports 0-1023 and accept all connects to port 1024 and above. this protects my system from connects via telnet, ssh, ftp aso., but are there any of the upper ports that i should block as well ? i left them untouched, because data is transfered on the higher ports after connection has been established. -- gruss,jens --------------------------------------------------------------------------- instant networks - netzwerkmanagment & internetfullservices
