Network Address Translation
(NAT)
Nokia E90 Communicator 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 net call settings, the NAT
settings cannot be defined manually, and it is therefore
recommended to use provisioning offered by the net call
service provider.
Note that NAT settings can be provisioned with an OMA
client by using a Nokia Intellisync Device Manager
(OMA DM) server. For more information about
provisioning, see forum.nokia.com. Note also that NAT can
be handled by SIP service providers, too, when they have
Session Border Controller (SBC) available to handle the
NATted client connections.
