Disabling the Teredo Tunnelling Pseudo Interface
The Teredo Tunneling Psuedo Interface is designed to allow IPV6 'traffic' to travel over an 'IPV4' network, however in some circumstances it can cause problems for VirtualRPC on a network with mixed IPV4 and IPV6 devices.
Almost all current networking hardware/software is IPV4, but the world is running out of possible addresses that IPV4 can support. The solution is to move to the newer IPV6 that supports many more possuble addresses. VirtualAcorn products are fine on IPV4 or IPV6, the problem happens when Windows uses the Teredo Tunneling Psuedo Interface to provide an IPV4 wrapper around IPV6 communications.
It's easily to find out if Windows has enabled the Teredo Tunneling Psuedo Interface:
- Open the Command prompt (Click Start then click All Programs then click on Accessories)
- Type ipconfig -all'
You will now see a list of the current network interfaces, you are looking for this:
If Windows has enabled the Teredo Tunneling Psuedo Interface then some part (or more likely almost all) of your network is IPV4 compliant. So disabling the Teredo Tunneling Psuedo Interface will not impact on your networks performance. To disable the Teredo Tunneling Psuedo Interface follow these instructions:
- Open the Windows Control Panel.
- (If the Control Panel is in 'View by : Category' click 'System and Security').
- Click Device Manager (if the UAC prompt appears click OK).
- In the Device Manager Window open the View menu and click on Show Hidden Devices.
- Find the Teredo Tunneling Pseudo-Interface in Network Adapters.
- Right-click on the Teredo Tunneling Pseudo-Interface and click on Disable.
You may need to restart your PC after making this change.
