Hello All,

I need to impliment QOS over my WAN to support QOS. I have a relatively simple network and do not need multiple levels of QOS. I have looked at applying a mangle filter to all UDP/5004 packets and giving them higher priority than all other traffic. Could you take a look at what I came up with and let me know if I am on the right track?

Thanks

Stephen

Hi Stephen,
It's not a good idea to apply QOS by port as ports are dynamic. VoIP traffic by default(most) uses DSCP value 46 to prioritize. This value is equal to TOS 184, and Mikrotik's Priority 3. So, with some help with our friends on the forum, I've put together the script below and it seems to work pretty well.
I hope this helps.

Seth
