Internet Application Problems
My online game does not work.
Cause:
The NAT table has filled up.
The correct settings have not been used to open the correct ports for
your application.
The unit has stopped working or crashed.
Resolution:
If you are trying to connect to game servers and your connection has
stopped working, wait a few minutes or turn the unit off and then on
again. Games send out many requests to many different servers trying
to find the best game server for your connection. When this is done, the
NAT table used in the Broadband Router can fill up and stop working
temporarily. Try using the DMZ host feature while connecting to game
servers and then disabling DMZ while playing the game.
Turn the Broadband Router off and then on again to reset the NAT
table.
Make sure that the correct ports have been opened in order for your
specific game to operate correctly behind a firewall. Consult your game
documentation or contact the technical support of the game company to
obtain the correct settings for your game.
Some games just won’t operate correctly behind a firewall. In this case,
use the DMZ host feature while using the game, then turning DMZ off
while the game is not being played to ensure proper firewall protection.
