Iptables & Voip
Everyone,
I would like to use our gateway linux machine to give bandwidth preference to voip udp packets. Can anyone point me to a tutorial about the use of voip and iptables?
I usually prefer to use iptables instead of firewalld. iptables is more intuitive, and easier to understand.
Thanks much!!!

One thought on - Iptables & Voip
Arch Linux wiki has nice explanations and examples:

Well, iptables is “closer to the metal”, for traffic shaping you would probably need to use raw rules in firewalld so, in fact, iptables anyway.
Depending on your setup complexity and preference you might not need iptables either and just use tc alone.
