NAT Test

Hi,
what are the differences between the client_nat_test function of the mediaproxy module and the nat_uac_test function of the nathelper module?

Thanks in advance,

C.

iirc, the mediaproxy function tests for a private address in the contact header, a private source IP address, and a private address in the Via header.

nat_uac_test() checks all the above, tests the ports as well, and tests the SDP. the mediaproxy functions may do that also.. i'm not that familiar with the code.

...and yes, we dont need both functions to do the same thing.. there is work planned on abstracting nat functions that are not application specific into a separate module.

Thank you for your answer,
so, you agree with me, we don't need both functions to do the same thing.
But can I make a cross thing like using client_nat_test (--> mediaproxy) and fix_nated_register (nathelper) or viceversa?

Thanks in advance,

C.

not without dipping into the source.. but not sure what you would gain by doing that? what are you trying to accomplish?

I'm tryng to do what described here:

http://www.openser.org/docs/modules/1.3 ... tml#AEN218

loadmodule "/lib/openser/modules/mediaproxy.so"
loadmodule "/lib/openser/modules/nathelper.so"

modparam("mediaproxy", "natping_interval", 0)

modparam("nathelper", "rtpproxy_disable", 1)
modparam("nathelper", "natping_interval", 30)
modparam("nathelper", "sipping_from", "sip:ping@sipserver.net")

modparam("registrar", "nat_flag", 6)
modparam("registrar", "sip_natping_flag", 2)
....
....
if (method=="REGISTER") {
setflag(6); # nat
setflag(2); # sip_ping
if (!save("location")) {
sl_reply_error();
}
}

But 'sip_natping_flag' doesn't exist anymore in 1.3 ,so I think I have to use modparam("nathelper", "sipping_bflag", 7).
Can you suggest me the better way to use mediaproxy in conjunction with nathelper in order to detect and fix the NAT properly and ping (i.e. send OPTION or NOTIFY) natted clients?
Thanks in advance,

C.
