I have been using openser as an ALG for the purpose of NAT traversal.
Unfortunately my public IP is dynamically assigned. Although openser is aware
of the IP's available on the host, I have searched unsuccessfully the
documentation for a way to expose this information to the configuration
script.
Have I missed something?
I am using the following ugly work around.
DHCP client writes to /var/openser/my-ip
From the rtpproxy init script -
OPTIONS="-l 192.168.1.1/`cat /var/openser/my_ip` -s udp:localhost:12221"
from openser.cfg -
route{
# get our public ip, this happens only once
if !$var(ip_initialized) == "yes"
{
xlog("L_NOTICE",
"****************************************************\n");
xlog("L_NOTICE", "*** Initializing the IP for masquerading SIP
Contact\n");
exec_avp("cat /var/openser/my_ip", "$avp(s:pub_ip)");
pv_printf("$var(my_ip)", "$avp(s:pub_ip)");
xlog("L_NOTICE", "*** New public IP is
<$var(my_ip)>\n");
$var(ip_initialized) = "yes";
};
