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")
I am using kamailio v4.3.1:
