Weird connection behavior



  • Not really sure what to put as an accurate title for this.  I'm pretty stumped.

    So yesterday, WoW put out an update.  I started the download and it gave me the little warning error icon.  This is normally it bitching that I don't have any incoming ports open(I'm assuming it uses uPNP normally).  Usually the download will still work, but it'll take longer.

    This time, when I connected on the connection info, it shows no connections at all.  Now that's unusual.  Also, the progress bar was moving, albeit very slowly.  So it's connecting somehow, but not showing anything for some reason.  I figure it's probably Snort complaining or something similar.

    Looking at the RRD and traffic graphs, my incoming connection is maxed out at 25mbps.  However, there's only 6-7mbps heading to my desktop.  The rest of my network is quiet.  I'm only using 1.6k states and my cpu processes actually dropped for some reason.  top shows both cores at 70% idle.

    I'm running pfSense 2.0 with squid, lightsquid, squidgard, snort, vnstat, nut, HAVP(I think that's all of them).  squid is set up as a transparent proxy with HAVP set as a parent to squid.  Snort has almost all of the rules enabled except for chat and p2p, IIRC.

    Any ideas what is going on?  Or where I can look to try and track it down?  AFAIK, the system wasn't putting out any errors anywhere.



  • During the updates via wow, run netstat in a cmd window to see what connections are being made / established.

    also on your RRD graphs, did you look @ the blocked traffic? Maybe it was blocking a crap ton of peers from the WoW community hammering at your firewall trying to upload data…

    I believe the connections window for the blizzard updater only shows you connected peers, not http/ftp connections.

    I'll take a look when I get home if it hasn't finished.

    What blocked traffic?  I couldn't find anything anywhere showing things were being blocked.

    No, it normally shows the http connection as well.



  • So it looks like HAVP was the culprit.  Once I disabled it, the download worked correctly.

    Not sure why it was causing so much chaos.
