Can't define Packet filter port ranges

We tried:     dst portrange x:y   dst portrange x-y   tcp portrange x:y   tcp portrange x-y   port x:y   port x-y     Nada. Gui rejects them all.

Doh... thanks for catching that. I think we upgraded libpcap to 0.9.4 in 11.3.0 as part of BZ391286. That change should support the portrange keyword.

 

 

Prior to that, you can use this syntax:

 

(tcp[2:2] >= 4000 and tcp[2:2] <= 5000)

 

 

This uses the tcp offset for dst port (tcp[2:2) to create a range.
