iptables -A FORWARD -p tcp --dport 6660:6669 -j DROP would
do, but, considering IRC servers also run on other ports,
you should do:
iptables -A FORWARD -p tcp -m multiport --destination-port
<insert random ports separated by comma here>
443 is used by https, so I don't think you should block it.
An IRC daemon would not normally run on that port.

Maybe best match will be achieved with l7-filter.sf.net

Dear All,
I am new to linux.
I want to disable chat with iptables so that nobody can use chat with
mIRC with LAN. Because every students are chatting all the time.
I am using Red Hat 9 and Squid.
They use port 443 and 6667 to chat with mIRC
How can I write firewall rules.
Any help is appreciated
