I have a Cisco DPC3825 DOCSIS 3.0 modem/router combo. I want to monitor the traffic that passes through my router such as bandwidth usage.
I have bandwidth meters like DuMeter on my PC to monitor traffic that goes through the PC. But I have other devices like my PS3 or mobile devices that connect wirelessly and I want to monitor that traffic as well. So I can have a more accurate log of bandwidth usage.
I need some sort of router software to do so. The only way I can do so is by installing some custom firmware for the router. Now I don't think there's any custom firmware for this specific device and the fact that it's both a modem and router makes it troublesome to install custom firmware.
My motherboard actually has two ethernet ports. I read a method where one can mirror all packets going through the router and forward it all to a spare ethernet port on the router. I'm thinking of connecting port 4 to the spare ethernet port and having packets mirrored to port 4. Does anyone have any more information on this method?
Alternatively I'm also looking into a separate router that either has such a feature or is moddable to install custom firmware to do what I'm looking for. I'd like one that's relatively cheap < 100 and can support 50+ Mbps throughput.
the router might be featuring a web interface or something like that...see the documentation of router to see the support it offers.. – Vineet Menon – 2012-02-09T07:04:22.887
