Right, sort of. To the extent that it works. It doesn't actually do everything you
think it should, and, it's somewhat dependent on the version of JunOS as to
how well it does or doesn't work.

I'm not unfamiliar or uninitiated in this regard. I had tickets with Juniper for
over a year and it escalated quite high up their escalation chain before they
finally admitted "Yeah, Services JunOS is different and it behaves differently
and if you need to do what you're trying to do, you should buy an M or MX
series."

It's quite unfortunate. I'd really like for the SRX series to not be so crippled for
my purposes.
