    Default Evo WiFi Controller - Active TCP Sessions

    Just had a need to do some work on our Internet Router (a Draytek) and noticed the Evohome Controller had over 300 active connections to the outside world.
    Seems a lot so I powered down the Controller and then let it run again for half and hour.
    Active TCP sessions above 200 again - all to the same host IPs but that many simultaneous connections? (204.141.57.101, 12.149.218.73 port 443)
    It must be swamping the Host Server.

    Anybody else confirm this via their Internet Router ? (NAT table or Data Flow Monitor)

    Are you sure they're active and not in TIME_WAIT?

    Unless it's causing you a problem, I wouldn't worry about it.

    mine is the 20's, measured by the same method (Draytek data flow monitor).
    I haven't wiresharked it...

    20's would make more sense - mine is back around 250... even if you allowed a couple of connections per 'device' (of whatever description or purpose) if should be sub-50...
    Time for Wireshark indeed.

    What is the firmware version of your WiFi Controller?

    Check that you don't have your NAT timeouts set too short on your router. (Might not be adjustable)

    If the connection is idle for a long time the NAT table may time out the entries and force the controller to establish a new connection periodically. Depending on where you monitor the connections from (anywhere except the routers own NAT table) it may look like there are a lot of connections open at once but all but one of them will be dead!

    If all the connections are in TIME_WAIT surely you don't have an active connection to the server ?

    On the other hand I did notice the iPhone app this morning saying that the servers were "down for maintenance", yet following the link to the website says everything is operational - take your pick.

    Quite. I was surprised.

    I'll test mine at some point because I'm now curious. The easiest way for me to do that is set up one of my Pi's as a SoftAP for the Evotouch to connect to then I can intercept all its traffic and run tools like tcpdump on the Pi. Just a matter of trying to find the time to do it....
