Thank you for this info oj88... I'll have to study this rate-limit more in order to implement In any case, called PLDT and the agent was able to resolve my issue. I just complained I'm not getting my stated 25Mbps. And they did something on PLDT end and asked me to stop the ONU for 4 minutes and check again. No more always 5Mbps "download" bandwidth from some IP address. Do you mean deep packet inspection? application-level determination? ERX does know which apps are using the packets.
