Double NAT - Definition

A Double NAT is a networking situation where two devices perform Network Address Translation. It occurs when data has to pass through two routers before the internet.

This networking situation causes issues with VoIP service. Some examples are:

  • Deregistrations of phones on the network
  • Dropped calls
  • One-way audio

See why 100,000 companies trust Nextiva for VoIP service.
