We are small WISP, and using CCR1009-8G-1S-1S+ for core router where are terminated all users (pptp), and this is point of Queue-ing and NAT-ing.
So, are this RB too weak for traffic of 300 Mbps and more, and have 35.000 connections, because CPU are over 50-60% on this usage, and most of CPU are using by Firelwall (i think NAT-ing) ?
Is there some trick how to cut down CPU usage or buy 1036 board ?
