Hi,

I am  hitting bit of a wall here.

- I am setting bflags for NAT, and SIPPING before save("location") however,
when I do "kamctl ul show", the Cflag is 0.

I also checked see if the bflags are set or not in the register routine -
they are being set.

What am I missing?

snippets of the config files.

#!define FLB_NATB 6
#!define FLB_NATSIPPING 7
modparam("nathelper", "natping_interval", 30)
modparam("nathelper", "ping_nated_only", 1)
modparam("nathelper", "sipping_bflag", FLB_NATSIPPING)
modparam("nathelper", "sipping_method", "INFO")
modparam("nathelper", "sipping_from", "sip:pinger(a)50.62.1.7")

# params needed for NAT traversal in other modules
modparam("nathelper|registrar|usrloc", "received_avp", "$avp(RECEIVED)")
modparam("usrloc", "nat_bflag", FLB_NATB)

# Caller NAT detection route
route[NAT] {
#!ifdef WITH_NAT
        force_rport();
        if (nat_uac_test("19")) {
                if (method=="REGISTER") {
                        fix_nated_register();
                } else {
                        fix_nated_contact();
                }
                setflag(FLT_NATS);
                setbflag(FLB_NATB);
        }
#!endif
        return;
}

# Handle SIP registrations
route[REGISTRAR] {
        if (is_method("REGISTER"))
        {
                xlog("L_ALERT", "REGISTER: From $fU, $fd  To $tU, $td");
                if (isflagset(FLT_NATS) || isbflagset(FLB_NATB))
                {
                        setbflag(FLB_NATB);
                        # uncomment next line to do SIP NAT pinging
                        setbflag(FLB_NATSIPPING);
                }
                # 7/28/11 - make sure only one contact location is active
                # at any given time
                # unregister("location", "$rU");
                if (isbflagset(FLB_NATB))
                {
                        xlog("L_ALERT", "REGISTRAR: For $fU, $fd  FLB_NATB
set");
                }

                if (isbflagset(FLB_NATSIPPING))
                {
                        xlog("L_ALERT", "REGISTRAR: For $fU, $fd
 FLB_NATSIPPING set");
                }

                if (!save("location"))
                {
                        xlog("L_ALERT", "REGISTRAR: From $fU, $fd  Location
could not be saved");
                        sl_reply_error();
                }

                exit;
        }
}
