How to Limit Bandwidth of P2P Traffic

This document applies to the firmware version ReOS v10.
 
User Requirements
 
An Internet Café wants to limit the bandwidth of P2P traffic: the maximum upload rate of P2P traffic allowed for each LAN host is 512Kbit/s, and the maximum download rate is 1024 Kbit/s. However, the internal servers (192.168.100.251 to 192.168.100.254) are exempt from this restriction.
 
Configuration Steps
Login to the Web UI of the UTT router, and then follow these steps.
