All,

Just to confirm that, as tested on the bench on SRX 3600 and JunOS 12.1R6.5 *all* packets processed by the DNS alg count as a "drop" in the output of "show security flow statistics", even though they're forwarded correctly.

The SUNRPC alg seems to do the same; presumably the all do.

So, if you have any ALGs enabled, that counter is misleading, and if you don't, DNS packets will consume a lot of your sessions.

This is demo model so I can't open a support case, but when the real kit arrives, maybe I will...
