I apologize the last sentence of my previous email should be "...but no OPTIONS pings on client's side"


Now I have installed kamailio 4.2 on server and client is behind NAT with enabled NATSIPPING and the result is the same like on private network = no OPTIONS ping. The only changes in default kamailio.cfg are:


#!define WITH_MYSQL

#!define WITH_AUTH

#!define WITH_USRLOCDB

#!define WITH_NAT

#!define WITH_NATSIPPING



alias="89.187.145.51"

listen=tcp:89.187.145.51:5060

listen=tcp:127.0.0.1:5060


modparam("rtpproxy", "rtpproxy_sock", "udp:127.0.0.1:7722")

# ----- nathelper params -----

modparam("nathelper", "natping_interval", 10)

modparam("nathelper", "ping_nated_only", 0)

modparam("nathelper", "sipping_bflag", FLB_NATSIPPING)

modparam("nathelper", "sipping_method", "OPTIONS")

modparam("nathelper", "sipping_from", "sip:pinger@89.187.145.51")

# params needed for NAT traversal in other modules

modparam("nathelper|registrar", "received_avp", "$avp(RECEIVED)")

modparam("usrloc", "nat_bflag", FLB_NATB)


and


route[REGISTRAR] {

      if (!is_method("REGISTER")) return;

      if(isflagset(FLT_NATS)) {

                  setbflag(FLB_NATB);

                  setbflag(FLB_NATSIPPING);

                   }

        if (!save("location"))

        sl_reply_error();

        exit;

}


After registration the Cflag is 192 so in my opinion nat_bflag and sipping_bflag are set but no OPTIONS pings on clint's side. I understand that it is  trivial problem but would somebody be so kind to help me to solve it?


Thank you


Petr

Thank you very much Daniel.

 

I have adjusted the parameter for nat_uac_test() to 128 without success.

 

Then I disable NATDETECT route and only load modules nathelper and rtpproxy and set their parameters to

modparam("nathelper", "natping_interval", 10)

modparam("nathelper", "ping_nated_only", 0)

modparam("nathelper", "sipping_bflag", FLB_NATSIPPING)

modparam("nathelper", "sipping_method", "OPTIONS")

modparam("nathelper", "sipping_from", "sip:pinger@192.168.1.44")

 

modparam("nathelper|registrar", "received_avp", "$avp(RECEIVED)")

 

and

 

route[REGISTRAR] {

      if (is_method("REGISTER")) {

               setbflag(FLB_NATSIPPING);

               if (!save("location"))

               sl_reply_error();

               exit;

}

}

 

 

 

cflag after registration is 128 so in my opinion FLB_NATSIPPIG flag is set but OPTIONS pings on client's side.

 

kamailio.cfg please you find attached

 

Thank you

 

Regards

 

Petr

Hello,

if you are in a private network, you need to adjust the parameter for nat_uac_test() function to ignore private addresses in check tests -- see the readme of nathelper module.

Cheers,
Daniel

Dear sr-users,

 

I am beginner and apologize for bothering you with such a trivial problem.

I would like to test sip UDP and TCP keepalive pinging. Kamailio and client  are on the same network (192.168.1.44 and 192.168.1.20) that implies not behind NAT. So in kamailio.cfg I have set

 

modparam("nathelper", "ping_nated_only", 0)

 

My simple kamailio.cfg please you find enclosed.

From logfiles on client's side implies that neither UDP nor OPTIONS pings are sending from kamailio.
If somebody would be so kind to help me I will be very glad.

 

Thank you in advance

 

Regards

 

Petr
