Inbound Traffic Blocked?



  • Hi,

    I am having issues with Dynamic DNS … but it falls back to what looks like inbound traffic being blocked (i.e. I can't web browse to support.easydns.com - requests go out, but nothing seems to come back ... :(). I have tried looking at the logs, but only outbound (Direction=OUT) traffic seems to be logged, not inbound traffic.

    Do I have something configured wrong, or is inbound traffic not logged? Is there a way to turn it on? Sorry if this is a dumb question ... :(.

    Thanks!



  • By default, only inbound WAN traffic that is blocked is reported in the logs. You can turn on full logging, meaning that it will log all traffic. Generally that is only used for debug as it will generate a LOT of data. You might be getting return traffic from the last person who had the IP address before you.



  • Hi,

    Yep, makes complete sense - and agreed on the traffic! I'm trying to debug a problem, hence the question. Do you know where to enable incoming logging? I admit, I have searched, and can't find it (likely me though … :().

    Thanks!



  • Easiest way I know to track valid traffic is to create a "pass" rule for the traffic and enable logging in the rule.

    Just remember to disable the rule when you're done….



  • Hi,

    Yep, I can add a custom rule (and remove it later, agreed there! …  ;)) - but I'm really after enabling the (default?) rule that exists now, in other words, logging traffic as it is already being passed / filtered. Is there a way to do this?

    Thanks!



  • You can drop into the command line and use tcpdump to watch the traffic. There is also a place in the GUI under diagnostics that you can also run tcpdump. This will show you all the traffic as it goes by.



  • Yep, makes sense - thanks!

    I'm actually trying to get it to syslog so I can send it to an external (remote) syslog server, for more detailed debugging, and also traffic analysis.

    Thanks again.
