Hi all,
I need to allow RTP packages on my network, but don´t want to
allow all UDP (And then ill try to priorize it), so i think i could do
that using u32. I can see that all packages that are RTP have a field
80 00, as shown below (It is the protocol version and payload type):
0000 xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx
0010 xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx
0020 xx xx xx xx xx xx xx xx xx xx 80 00 xx xx xx xx
Could someone give me a tip on how should the u32 filter look like?
Thanks a lot,
Rafael Gustavo Gassner
