I'm new to Allstar and Asterisk, and I've taken several days to poke around and understand how everything works together. I'm interested in creating a private network with node registration, similar to how Allstar registers and coordinates node numbers. Based on everything I've absorbed in the last week or so, it looks like the crucial step is the IAX2 registration that hits register.allstarlink.org with the node number and assigned password. To recreate a centralized server to handle node assignment/registration, it looks like I need to run a copy of Asterisk (in one configuration or another, with or without app_rpt?) on a public server. Now the details get fuzzy because I don't know what goes on behind-the-scenes on the Allstar server. Looking at iax.conf, it appears that the central server would need stanzas for each node that is authorized on the system, set up as type=peer and host=dynamic. Once the iax.conf file on the node server is configured to register at the central server with the correct node/password combo, it should register once IAX2 is reloaded. I've gotten this far on my own, with one issue: the registration process shows 192.168.1.1 as the other server's IP address, rather than the WAN IP. I'm not immediately sure why, but one possibility is that since I'm running both servers within the same LAN, it may not be reaching outside the network for an external IP. In my register statement I'm using the WAN IP, however. I will have to move the one server outside the LAN to see if the issue resolves itself. So can someone fill in any gaps, or confirm my assumptions? What steps do I need to do in order to create a private Allstar clone? I'm a senior PHP developer with some C experience, plus I'm comfortable with Linux in general. Just need some help figuring out how the central Allstar servers keep track of nodes. Thanks! Rich N2DLX
