Do you mean something like specifying tpc port 135 through 139 in a
single rule?

iptables -A INPUT -i $EXTIF -p tcp --dport 135:139 -j DROP

If you mean non-contiguous ports, you're looking at multiport:

iptables -A INPUT -p tcp -m mulitport --dport 21,25,80,110,143,443 -j
ACCEPT

Multiport is limited to 15 ports per rule.

j
