<font face="Courier New, Courier, monospace">Hello;<br>
at registration route , you can use nat traversal function , there
is a sample on kamailio.cfg<br>
that parameter is just adding from and request header for
information on OPTIONS packet. you can add your 120.XXX.XXX.XXX <br>
<br>
Cheers.<br>

<br>
<br>
Thanks for your advice!
<br>
<br>
I searched nat_traversal in kamailio.cfg in PCSCF module, and
found that I should define WITH_NATPING.
<br>
<br>
After doing this, a new problem came. What does this line mean?
What should I configure to replace
<br>
"sip:keepalive@HOSTNAME" ? Is this HOSTNAME a turn/stun server?
<br>
<br>
modparam("nat_traversal", "keepalive_from", <b>"sip:keepalive@HOSTNAME"</b>)
<br>
<br>
<br>
#!ifdef WITH_NATPING
<br>
# ----- nat_traversal params -----
<br>
# If another keepalive is wanted, this is the place
<br>
modparam("nat_traversal", "keepalive_interval", 20)
<br>
# If another method than NOTIFY is wanted:
<br>
modparam("nat_traversal", "keepalive_method", "OPTIONS")
<br>
# From?
<br>
modparam("nat_traversal", "keepalive_from",
"sip:keepalive@HOSTNAME")
<br>
# Where we store information about keep-alives:
<br>
modparam("nat_traversal", "keepalive_state_file",
"/var/run/kamailio/keepalive_state")
<br>
#!endif
<br>
