Hi Daniel,
Thanks for that information, I had a look at registrar/nathelper and usrloc
module documentation, and I do see the server_id parameter in the usrloc
module docs for v4.3.x. This appears to be a database only column, I am
running in memory only mode using dmq_usrloc to replicate the registrations,
in this particular instance, how would I go about setting the server_id
parameter when running in memory mode (db_mode 0).
Thanks

You have to set server_id to be different for each node in order to send
keepalive only for registration received directly, however, iirc, this
feature is only in master branch.
Cheers,
Daniel

some more info on this one, it looks like this is only
happening on
nodes that have been replicated to, for example,
If a registration is processed on node 1, then the nathelper send the
locally generated options message out of the correct socket, I presume
it gets the sending socket details from the socket information stored
by the registrar. (Socket:: udp:10.7.0.175:5060)
However, when this registration is replicated (via dmq_usrloc), there
is no local socket information for the particular contact, the
nathelper module seems to think that it needs to ping this
registration contact (it is natted) and sends it out of the wrong
interface even if the force_socket module parameter is set for the
nathelper module.
That brings me on to my next question, why is the nathelper module
attempting to ping natted contacts from all registrar's, should it not
ping from the registrar that processed the last registration attempt?
I had a read of the nathelper module documentation, but I cannot see
any obvious setting that would tell nathelper to only ping from the
registrar processing the request.
Is my understanding of how nathelper is supposed to work correct when
it comes to multiple registrar's with registration replication? Myabe
I am missing something here, any tips/tricks/suggestions/beatings most
welcome
Thanks

Hi All,
I have a strange issue, I have set the module parameter for
nathelper's force_socket to a specfic ip/port, however, when I
perform a sip trace I can see that all locally generated options
messages are not sent from the socket defined in the modules parameters.
I am not setting $fs anywhere in the script, so I am not over-writing
it. Do any of the other module parameters have a bearing on if
nathelper uses the force_socket parameter?
My current nathelper settings are:
modparam("nathelper", "received_avp",
"$avp(RECEIVED)")
modparam("nathelper", "natping_interval", 20)
modparam("nathelper", "natping_processes", 4)
modparam("nathelper", "ping_nated_only", 1)
modparam("nathelper", "sipping_from",
"sip:keepalive@domain.com")
modparam("nathelper", "sipping_method", "OPTIONS")
modparam("nathelper", "sipping_bflag", NAT_BFLAG)
modparam("nathelper", "force_socket",
"1.2.3.4:5060")
