Re: [BW Meter] New comcast internet service flooding modem said by Ryoukidnme:Continually flooding my new account after 5th day of service 40% of 250gb bw limits. Can you post a screen shot of your meter?
said by Ryoukidnme:All i get is tons of logs from this remote mac that is using tons of different ip addresses and this is the beggining of the logs:
[Firewall: RF_Port_Filter]
It has DST-MAC and DST and then SRC-MAC and SRC
no ports or type of attack but the SRC-MAC is always the same. The SRC is always a different ip address
The DST-MAC is my modem mac and the DST is my modem ip address
Can you please post a screen shot of your logs?
"Areis" isn't a maker of cable modems.

| I have a smc modem. this is a portion of the logs the blacked out DST-MAC AND DST is my modem MAC address and modem ip address
Comcast claims the SRC-MAC is an Arris modem(sorry for the spelling) but anyone can look up a mac or spoof a mac.
The probelm with asking for help is all the solutions provided are surrounding the concerns of the lan internally such as anti-virus firewalls and such. But this is a SMCd3gmv modem/router/voip the logs are coming from this firewall. and my concern is comcast bw meter. if anyone as myself gets flooded 24/7 with packets then i or the customers are not getting the services claimed the 250gb bw cap. From unauthorized usage. Which is fraudulent bw metering. I dont want my service flaged or turned of because this bw meter is being bled out .
Note i checked the account at 1:30 am and noticed now the comcast bw meter has now changed to 20% of 250gb from 40% of 250gb which happened sometime after speaking to 4 comcast reps that could not provide me with a solution for this problem.
I believe with a proper letter addressing this issue fcc and federal court could outlaw bandwidth meter due to all the unauthorized traffic that can run up the meter without any way to stop this by the isp or customer. BW meter is a flawed idea. There is no way to actually offer 250gb of bandwidth to a customer. Also with many articles online claiming isp flood connections with closing commands to throttle services as they chose, if this is so then this is another reason why bandwidth caps are fraudulent.
This is a serious issue threating service of every isp customer that has bw caps.
Thanks for your input and thanks comcast for lowering the % its gonna have to be continually lowered if the flooding continues. |

kudos:2 | Ok. I think there's two separate issues here.
One, is the typical probing of (likely) infected PCs connected to the Internet. Everyone gets this and if the firewall is doing it's job, it's dropping the connection requests. If I looked in my router's firewall log (which I rarely do unless I have a need to), I would see similar entries and to my knowledge, have never had any obscene usage show up in my meter that I was concerned about. BTW, I have my SMC in bridge-mode as many of the functions are duplicated with my existing network, which I prefer to use.
If you want to take up the issue of BW metering with the FCC, that's your decision, but your using a shaky foundation to build your case against it. I still suggest you post in the Direct forum and have one of their reps look into the meter and why it is showing usage you can't account for. I also suggest you setup your own metering so you can compare your readings with Comcast's.

In the first 5 days of service, according to you (I haven't seen a screen shot yet) the meter indicates 20% of 250 GB or about 50 GB of data used.
What have YOU been using your connection for since you had it installed?
What kind of connection did you have before the cable modem was installed?
The firewall logs look like standard background chatter caused by broadcast packets being relayed through the CMTS (lookup Proxy ARP). Arris is a manufacturer of CMTSs. Everyone averages around 5 GB of background chatter per month on the average cable hookup. It seems Comcast ignores it in there bandwidth calculations for their customers.
Your letter to FCC/Federal Court won't work, you'll need actual proof. Start with a meter on your side of the link measuring the traffic you use. Then compare it to Comcast's meter over the course of a few months. Most people find when doing that, Comcast's meter is accurate within a few GB.
