Whether you’re using the Nintendo Wi-Fi USB Connector, the Wii LAN
Adapter, or a wireless router, firewalls and other computer security
programs can be very tricky to get working when attempting to do
online gaming. Anti-virus, anti-spyware, software firewalls, and
firewall-enabled routers can affect communications within your network.
You may want to consider temporarily disabling, or removing, these
products installed on home networks to enable game play. If this
is not the approach you wish to take, below are some guidelines for
how your firewall or security program needs to be adjusted. As each
manufacturer is different, if you need help making these adjustment,
please contact your firewall or security program manufacturer.
The following detailed information regarding required protocols,
ports and communication requirements needed by the Wii console,
games, and the Nintendo Wi-Fi USB Connector (if used) may be helpful.
Please consult your firewall’s instruction manual or manufacturer
for specific assistance on working with the firewall.
While Nintendo makes a concerted effort to test and document known
incompatibilities with software and hardware, it is impossible for
us to test and document them all. Detailed information regarding
the necessary ports and sites has been included below for those customers
who want to use and configure their own firewall or computer security
application.
Allowing TCP and UDP Traffic:
The Wii console may require unrestricted access to several sites across various
ports and protocols to function correctly. These addresses and ports vary,
and may change in the future without notice. Many software firewalls restrict
outbound access. Only if your firewall blocks outbound traffic do you need
to enable this traffic:
TCP:
Allow traffic to all destinations on ports: 28910, 29900, 29901, 29920, 80,
and 443
UDP:
Allow all traffic to all destinations. (Necessary for peer-to-peer connections
and game play). Our Network
Test tool can be used from
a computer behind your firewall to test if outbound UDP is allowed.
Please note that by allowing the traffic to the destinations listed
above, you are essentially removing a significant amount of firewall
protection for your network. While Nintendo provides this information
for our consumers’ use, it is up to each consumer to determine what
security needs they have for their own networks, and to decide how
best to configure their network settings to meet those needs.
Additional Information for the Nintendo
Wi-Fi USB Connector Users
If you are using the Nintendo Wi-Fi USB Connector, and have a software firewall
or other computer security program installed on your computer, there may be
additional steps you must complete to allow a successful connection.
“Trusted” IP Ranges:
There are also potential ranges of IP addresses that may need to be added
to the “trusted zone” for your software firewall or PC security program
for Nintendo Wi-Fi USB Connector users. Each of these would need to be
opened up for TCP and UDP traffic, or for some firewalls or security programs,
added as a “trusted zone.” Please consult the manual for your firewall
or security program for more specific information.
192.168.1.1 subnet mask 255.255.255.0
172.16.1.1 subnet mask 255.255.255.0
0.0.0.0 subnet mask 255.255.255.255
Software Firewalls Identified
as Being “Incompatible” with the
Nintendo Wi-Fi USB Connector
We have identified the following software firewall(s) as being incompatible
with the use of the Nintendo Wi-Fi USB Connector. We suggest using another
firewall product, if possible:
Turn off any “VPN” programs running
on the computer
Virtual Private Network (VPN) programs can interfere with the Nintendo Wi-Fi
USB Connector, and must be turned “off” or “disabled.” VPN’s are typically
found on computers belonging to those who need to create a secure connection
to an outside network (for example, people who work from home).
