We have implemented Asterisk SIP server & SIP client Zoiper on different machines in our lab.
Lab network is a internal private network & its connected to switches which is connected to DSL box for internet. There is no firewall comes into the picture. DSL box is doing the natting.
How can the same SIP server is used by the SIP clients installed on machines with public IP outside internal LAN ? What are the configuration changes required for the below mentioned two cases ?
For example :-
Case 1 :-
A UAC on LAN wants to connect to UAS (Internet with Public IP) outside LAN.
Case 2 :-
A UAC on internet (Outside LAN) wants to connect to UAS on the internal LAN
Kindly suggest your valuable inputs.
