Adding IPv6 Support to the Gateway (Windows Embedded CE 6.0)
1/5/2010
For security reasons, IPv6 is not enabled by default when it is added to the image. You can enable IPv6 with the sample network admin ISAPI only if the target device supports a persistent registry. Most sample CEPC images, for example, do not support a persistent registry.
Note
Unlike IPv4, IPv6 does not use the network address translation (NAT) functionality to connect to the external network. To avoid exposing internal systems directly on the external public network, you must configure the IP firewall on the gateway. For information about configuring the IP firewall to properly manage traffic destined for the internal network, see IP Firewall Reference.
Windows Embedded CE supports DHCPv6 Lite, which is similar to DHCPv6, but removes address configuration and the need for the DHCP authentication mechanism. DHCPv6 Lite can also be used to perform prefix delegation, that is, assign a prefix to clients behind a site gateway. For more information about DHCP, see TCP/IP and the DHCP Client.
Make sure that you understand the security consequences of enabling IPv6 routing on the target device by reviewing the IPv6 documentation. For information about changing the default behavior so that IPv6 is enabled by default during the build, see TCP/IP Security.
