[LARTC] how to define a port range?

[Thorsten Gehrig]

hi,
i´am new in tcc (tcng). i try to define my qos for VoIP-Services.
For this i wantto define a class for a port range 10000 till 15000.

how is the right way?
this down works:
class (<$voip>) if tcp_sport => 10000 || tcp_sport <= 10000 ;

are there any examples of real installations - maybe including VoIP,
HTTP and P2P services?

regards
