Subject: RE: Permit udp any range 16384 32767 any
Hi,
I dont know if this was answered but here is what i think. Correct me if
needed.
Cisco example 1 uses this to match voice data:
access-list 100 permit udp any any range 16384 32767 <<< coming in to
dest
If u see this example and link then the traffic is just getting clasfied
on the incoming Ethermet interface.The traffic is not two ways here. It
enters on Eth0/0 and u classsfy and perform QoS actions over it and hence
only "any any range 16384 32767" as the dest ports are the renages given.
In the next example
Cisco example 2 uses a different approach:
access-list 101 permit udp any any range 16384 32767 <<< source to dest
access-list 101 permit udp any range 16384 32767 any <<< return traffic
from dest
What is happening is they are considering both the traffic flows in each
direction as it says FXS to FXS.
So both are the same only that in example 2 they are considering return
traffic toooo
HTH.
Good Luck,
Kasturi
