Relay Mode
In
Relay mode,
the UT will supply the Global IP address to the
TE when the context is established. Relay mode is a single user
mode, as it only supports a single connected TE.
In Relay mode, DHCP is required to provide the Global IP
address to the TE. When the context is activated, the DHCP
server in the UT will NACK the next DHCP lease renewal from
the TE and assign the Global IP address assigned by the
network. The local IP connection will be torn down and
reestablished as the IP address changes. Similarly, when the
context is deactivated, the DHCP server will NACK the lease
renewal and then reassign the original private IP address.
The Web UI will lose and reestablish the connections to the
terminal as the IP address is changed.
To make the IP address change happen quickly, a short DHCP
lease should be used. The terminal defaults the DHCP lease
time to 60 seconds in idle and connected mode.
Relay mode only supports a single user TE.
NAPT Mode
In
NAPT mode
, multiple devices connected via a hub or switch
share a single PDP context. The port translating NAT modifies
both IP addresses and port numbers so multiple devices can
share the single Global IP address assigned to the PDP context.
In NAPT mode, only a single context is supported. By default,
an Always On Context is activated. The
ACA
Page is removed.
A
Port Forwarding
Page is added under
Settings,
and it can be
used to configure the DMZ and Port Forwarding parameters.
