Hi I would know if there is a metod to limit the number of UDP connection caused by p2p, I know that UDP is connection less but if I use an approach like this guide for a transparent traffic shaper (http://wiki.mikrotik.com/wiki/TransparentTrafficShaper) the p2p encrypted will not be catched and I can’t limit all connection different by http because I want skype, voip and other essential service, that use udp, working well.
You could try something like this.
Limits udp connections but not DNS requests.
/ip firewall filter add action=drop chain=forward comment="UDP Conn Limits" connection-limit=30,32 disabled=yes dst-port=!53 protocol=udp
Is this a right approach to prevent p2p congestion?
