[j-nsp] J4350 dropping DNS packets, no filters applied to interfaces

[Alex Campbell]

Hi all,

I'm seeing some strange behaviour on a J4350 running 8.2R2.4, and I'm
hoping someone can cast some light on what is going on.

Any DNS traffic that passes from our network to our upstream is dropped
by the router.  All other traffic makes it through fine.  What makes
this strange is that this still occurs even when I remove the firewall
filters from both of the interfaces.  I'm really not sure what else
could be causing the traffic to be dropped.

Any thoughts would be most appreciated.

Alex
