try:
iptables -A FORWARD -i eth0 -o eth1 -p tcp -s 192.168.2.0/24 \
-m multiport --dports 24,80 -d 192.168.1.2 -j ACCEPT

|- multiport uses "--dports" with an 's'
and what on earth is TCP port 24? should that be a 25, perhaps?
and "-m multiport" does not support byte ranges (21:23), use mport for
that, or a regular port match.
