Yeah, the one unfortunate ting in the J-series and SRX-series is that after 9.6
you have to put in a whole bunch of config to turn it back into a router.
JunOS on these "services" routers now wants to behave like a netscreen
until bludgeoned otherwise.  The way to achieve this is not intuitively
obvious, especially the forwarding-options mpls (which affects inet,
not just mpls) and the flow stuff.

Here's a useful template for those that care:

security {
    zones {
        security-zone trust {
            host-inbound-traffic {
                system-services {
                    all;
                }
                protocols {
                    all;
                    bgp;
                    ospf;
                    router-discovery;
                }
            }
            interfaces {
                all;
            }
        }
    }
    alg {
        dns disable;
        ftp disable;
        h323 disable;
        mgcp disable;
        msrpc disable;
        sunrpc disable;
        real disable;
        rsh disable;
        rtsp disable;
        sccp disable;
        sip disable;
        sql disable;
        talk disable;
        tftp disable;
        pptp disable;
    }
    forwarding-options {
        family {
            inet6 {
                mode packet-based;
            }
            mpls {
                mode packet-based;
            }
        }
    }
    flow {
        allow-dns-reply;
        tcp-session {
            no-syn-check;
            no-syn-check-in-tunnel;
            no-sequence-check;
        }
    }
}
