I am connected via
a home router and
my real time/gaming
applications are not
working correctly.
Your home router acts as a NAT (Network Address
Translation) device. After installing the TA, there are now
two NAT devices connected to each other. All Internet traffi c
is now going through double NAT. This is not a problem for
most applications, but some, especially real time gaming
applications, will not work correctly.
To eliminate double NAT, use the home router as a switch
by connecting the TA’s Ethernet port to the home router’s
LAN (Ethernet) port, instead of the WAN port. This way NAT
functions are bypassed in the home router and Internet traffi c
is only passing through single NAT (that of the TA). A crossover
cable may have to be used between the TA and router.
I keep getting
“activation fail”
during the TA
Activation process.
Make sure that prior to beginning the TA Activation process
you have disconnected from any secure client such as a
Virtual Private Network (VPN) client and that you are connecting
to the Internet through your cable/DSL Internet provider.
I forgot my PPPoE
username and
password. Where
can I fi nd it?
This information should have been provided by your DSL
service provider. If you cannot fi nd the information, please
contact your DSL service provider to obtain this information.
I may have a static
IP address but I’m
not sure.
Chances are you have dynamic IP addressing.
If you have a home router, you can check whether or
not your router is set up for static or dynamic IP using
your router confi guration Web page (see your home
router’s documentation).
If you don’t have a router, you should fi nd your TCP/IP
properties (in the Network Settings area of your computer
– see your computer’s online help or pages 26-27 of
this guide if you do not know where this is). If “obtain IP
address automatically” is checked, you have dynamic
IP; if “specify an IP address” is checked, you have static
IP. To be sure, you can also check with your cable/DSL
service provider.
I have DSL and
keep getting
“authentication
fail” for
connecting status.
1. Confi rm your cabling is correct according to Step 3.
2. Power all devices down and unplug your cable/DSL modem
and home router. Leave them off for at least 15 minutes.
Power up your cable/DSL modem and wait until all appropriate
indicator lights are lit. Power up your TA by plugging it into a
power outlet. Power up your router (if you have one). Turn on
your computer(s).
3. Check that your PPPoE username and password are correct
(your DSL provider may need to provide this information.)
