I have a private network like this:
+-----------------------+
| firewall |
+-----------------------+
|
+-----------------------+
| 1.2.3.4 |
------------------ | NAT |---------------------
| 192.168.1.1 |
+-----------------------+
+-----------------------+
+-------------------------------+
| PBX:192.168.1.2 | |
SIPphone:192.168.1.3 | ............
+-----------------------+
+--------------------------------|
Now ,I can let my asterisk work correctly by STUN.But ,for security,I
must config my firewall.Because the RTP port is allocated
dynamic(10000:20000),if I just open ports 10000:20000 on my firewall
,I doubt that it will not work.Maybe like this: asterisk get a RTP
port 10000,but after it get through NAT,the port become
9999(worse,next time it may be 9998,and i can't preknow it will be
what),then my firewall will DROP it.
Please help me ,thanks
