There used to be the following hidden command up to 8.5ES to switch back:

set security forwarding-options family inet mode packet-based

Looking at a v9.0ES box, it looks like packet-based is now available only for iso, inet6 and mpls

Hi,

In the ES version, there is a 1M-session potential bomb for J6530,
according to the spec sheet.

Start from 9.4, there is no non-ES version JUNOS for J-series box. I
am wondering if the command provided in KB can completely turns the ES
version JUNOS into non-ES version. Which means make the J-router
forgets there is a concept of "session".

That KB is to turn Junos-ES into a router device..

the first part:
           no-syn-check;
           no-syn-check-in-tunnel;
           no-sequence-check;

Basically turns off *all* state full tcp. At that point you might as well be
using stateless acl's.

The next portion is to disable the ALG's (application layer gateways). Again if the end goal here is to use this device as a router, I agree with it.

If you're trying to use the security{} options as a firewall then do *not*
follow that KB.

Good luck,
