2009/9/11 jun yang <yj13535428332@gmail.com>

the os have three ip, one public ipv4 with adsl which is dynamic assigned every time, two lan ip in diffrent scope, 192.169.0.2 ,192.168.5.2.
when freeswitch start ,it auto bind to the pubic ip, so the lan user cann't connect to freeswitch use lan ip.
i have setting
<X-PRE-PROCESS cmd="set" data="bind_server_ip=0.0.0.0"/>
but have no effect, freeswitch also auto bind to the public ip.
any help is thanks.
