  I dont understand your network setup - you have a mish mosh of
multiple ip's on same physical interfaces ... I suggest you clean up and
start fresh ... and stick with ip4 - turn of ip6 on all your interfaces.

  When you say the other interfaces are not active - they are active -
they may not have wire plugged in - but they are up and running ... if
you're using network service - i'd ifdown the entire bunch and go make
nice clean tidy files.

  If you're using nm-applet - delete them all - bring up the one you
want (with no duplicated ip's on the interface) and go from there.

  I am leaning toward this is not a firewall problem ...
