Iptables ip/port range spec:

Multiple individual ports:
iptables -t mangle -A OUTPUT -p udp --match multiport --dports 110,143,993,955 -j MARK --set-mark 13

Port Range:
iptables -t mangle -A OUTPUT -p udp --match multiport --dports 1024:3000 -j MARK --set-mark 13

Multiple Port ranges:
iptables -t mangle -A OUTPUT -p udp --match multiport --dports 1000:2000,3000:4000 -j MARK --set-mark 13

Port ranges and individual ports mixed:
iptables -t mangle -A OUTPUT -p udp --match multiport --dports 1000:2000,3000:4000,10,20,30 -j MARK --set-mark 13

IP address range:
iptables -t mangle -A OUTPUT -p udp -m iprange --dst-range 192.168.10.100-192.168.10.200 -j MARK --set-mark 13

IP address range (last octet range)
iptables -t mangle -A OUTPUT -p udp -m iprange --dst-range 192.168.10.80-100 -j MARK --set-mark 13
… matches ip address range 192.168.10.80 to 192.168.10.100

iptables -t mangle -A OUTPUT -p tcp -d 192.168.10.10/24 -j MARK --set-mark 13

Filtering specific ports
iptables -A INPUT -s 81.48.0.0/16 -p udp --destination-port ! 80 -j DROP
