Hi
I have build a sip environment
one pc A(red hat 9) as gateway , only enable NAT , and install ser with nathelper
notebook B get ip from pc A , register to PC A's public IP
notebook C is public and register SIP to pc A's public IP
+-------------------+
| PC C (Msn) |
+-------------------+
|
| Internet
|
+----------------------------------------+
| Gateway / NAT |
| Ser with Nathelper |
| PC A |
+----------------------------------------+
|
| Intranet
|
+-------------------------------------+
| PC B (Kphone 3.14) |
+-------------------------------------+
B call C , then C pick up the call , but voice from B to C can work , C's voice
can't make it
My question is Nathelper this module is now only for Cisco is Sip ... ? and is this module
need
STUN server ?
Now , for ser , how to solve NAT/Firewall 's problem ? or it's service
provider's issue ?
Thanks
