Hallo forum,
I have exactly the same problem attempting to connect to my main provider but let me provide additional details...
I am running two separare 3cx server systems, one on my pc physically connected to my router, the other on my laptop connecting to my router via wireless.
On my pc the application functions 100% and my external IP is presented to my provider but on my laptop, exactly the same settings, with the exception of port numbers which are all correctly forwarded in my router, I keep trying to send my private IP.
I have carried out the firewall check, all good, I have checked I can ping the stun servers, also all good and I also have an ap that checks my external address every 15 mins [also same on PC] but I can not get my external address out to my provider.
Further note that I have configured a bridge between the two machines, all good. I also have on my laptop another account which is normally deactivated so that I only access the service from my main pc, but if I do activate this service, this registers and I can make and receive calls.
So any ideas as to why I am attempting to send my private IP address to one provider and not others would be appreciated.
Get back to me if anything is unclear
Thanks in advance,
Antler
