Network Address Translation (NAT)

Nokia device supports STUN (Simple Traversal of UDP Through NATs) servers for NAT (Network Address Translation) traversal, for networks where you do not have a public IP address. Even with STUN servers in use it is possible that the connection will not work, as some types of NATs still block the traffic.

The settings for NAT traversal can only be provisioned by the service provider, for example over the air or via download, but cannot be edited manually by the user.

Unlike the SIP settings and Internet call settings, the NAT settings cannot be defined manually, and it is therefore recommended to use provisioning offered by Internet call service provider.
