>Description:
Why not exist a TCP/UDP port_table for IPFW? It can solve 30 itens limit in ipfw rule. It is good to use in QoS.

Example

ipfw add allow { tcp or udp } from any port_table(10) to any

ipfw port_table 10 add 20,21,25,110,443,993,995,1025-65535

# Deny bad ports
ipfw add deny { tcp or udp } from any to any port_table(11)

ipfw port_table 11 add 135,137-139,445

ipfw add queue 100 udp from any port_table(20) to any
ipfw port_table(20) add 123,53
