the 750gr3 is being used as the dude monitoring system. It connects to 3 different NOCs with public static IPs. I keep seeing red in the logs with mesgs about packet loss between these routers. I also keep seeing the gateways go down, but Charter says they didn't. I'm also seeing a TCP connection established from 139.162.102.46 and ditto for 59.111.30.195 in the log as well. I need to figure out how to block these as I don't think they should be there.

RB750GR3 is all gigabit, just like the RB3011. Which one is exhibiting packet loss? How much mbps and pps is each router passing to/from the modem at the time packet loss occurs?

suffering packet loss around the modem to my service provider (300MBps). (Not to be confused with suffering-succotash.) Could a RB750gr3 on one modem port (static IP) and a RB3011 on another port (own static IP) cause the situation? I think the 3011 is rated for GBps and the 750 is 100MBps.

    Jan, PPS are a function of CPU, memory, and how much data you can
    push through the system you are running. It is also dependent on
    how large of packets you send and how many small packets you are
    passing. Here a snapshot of a tower router RB2011 that is nearing
    its capacity. In the evening we get around 200MB but at 50% CPU
    usage.

    This is a snippet from Mikrotik documentation showing capabilities
    of this router.  Notice that with small packets throughput drops
    significantly regardless of how many packets per second it says
    you can pass through it.

            When you say modem, are you talking about a cable modem
            perhaps? Is it possible you're hitting the PPS limit on
            the device?

            When customers are doing 60 megs can you do a Speedtest
            and still hit 300?

            serious, approx 250Mbps, even when plugged directly into
            the modem. Speedtest via google, Bing and speedtest.com
            <http://speedtest.com> all show about the same thing.

            I recently bought an increase to the service speeds so I
            could compete better with DSL, Exceed and Gen5.

               They have replaced my modem about 5 times, yet
            customers who have not experienced problems before are now
            complaining.  I have a 300mbps service, now.  I see
            roughly 30-60Mbps peak traffic.

            I need a means of testing for various types of traffic
            across the threshold.
