Lookup tables with dst-port as argument

[Patrick Tracanelli]

Hello FreeBSD community,

I need to dynamically allocate filtering ports on a tuplet, table would do the job, can I lookup the port argument from a table? Something like:

ipfw add count all from “table(blist)” to any dst-port tablearg in 

In the above example table blist was created as “ipfw table blist create type number”.

It certainly won’t work as above written since tablearg is not supported for dst-port. 

Is there any other approach possible to reach this desired behavior?
