[Serusers] with private IP , I cann't hear the one with public IP

[gg]

hi everyone!

   I have installed ser-0.8.10 and ser-mysql-0.8.10 on Red Hat Linux 7.2. After I made a little configuration on the script (even did not add anything). The SIP server can work
well in LAN .There are Two telephones both in the LAN can get though. When I put ser on
Internet, and put the two telephones on Internet with their own public IP addresses, 
they can work well too. 

  Then I put one in a intranet with its private IP address, and the other on Internet with 
its public IP address, they can get through too. with the telephone with public IP 
ddress I can hear the other, But the other cann't.
 
   What's wrong? I have no idea what I can do .
   Anyone help me please ! 
   Thank you!
