Hi Everyone, I'm currently have an issue on a new PBX Migration so this current setup is not in production yet. The FreePBX instance I am running is current being hosted, has a public IP and behind a Managed firewall. From computers placed in to the voice VLAN they will receive an IP from the correct DHCP scope, have internet access, able to talk to FreePBX on port 83 and is able to download the config file. For DHCP I am using Microsoft DHCP server on windows 2012 and have DHCP option 66 configured to the pubic IP address of (not local loop back, not an unroutable internal address, or similar) the FreePBX server. When I connect a phone, DHCP seems to work as it gets an IP address from the correct scope, but It doesn't seem to attempt to connect to the FreePBX server. The results seem to be the same with different DHCP servers, a test windows 2012 DHCP server and SonicWALL Firewall DHCP server. I have verified that no traffic is seen on the FreePBX server with a TCP Dump, Managed firewall providers do not see the phone traffic hitting the firewall, and my outgoing SonicWALL firewall doesn't have any logs of it either. Currently I'm stuck on next troubleshooting steps, I would think it is a DHCP config issue but there doesn't seem to be much in the way verify. Any suggestions would be helpful.
