Which selection should I make in the Public IP screen on my DVC-1000?
Use Auto-detect public IP address when:
- Making calls over the internet.
 
Use Use Private IP address when:
- Making calls over the local network
 - Not connected to the internet
 - Connecting over a VPN
 
Use Specify public IP when:
- Making calls over the internet with a public IP address that isNOT the WAN address of your gateway/router. This would be asituation where multiple public IP addresses are available and arebeing mapped to internal IP addresses.
