Before You Begin
Before configuring proxy Mobile IP, you should consider these guidelines:
• You can enable proxy Mobile IP only on root access points (units connected
to the wired LAN). You cannot enable proxy Mobile IP on repeater access
points or bridges.
• Access points participating in proxy Mobile IP should be configured with
gateway addresses. You can configure the gateways manually, or the access
points can receive gateways through DHCP.
• The foreign and home agents must reside on the network gateways where you
want to support proxy Mobile IP.
• If your authoritative access points receive their IP addresses through DHCP,
use the access point host names to specify the AAPs in the proxy Mobile IP
configuration.
• Proxy Mobile IP does not support broadcast and multicast traffic for visiting
clients.
• To use proxy Mobile IP with DHCP-enabled client devices, you must disable
Media Sense on the client devices. You can find instructions for disabling
Media Sense in Microsoft Knowledge Base Article Q239924. Click this URL

• Proxy Mobile IP does not support VLANs.
Configuring Proxy Mobile IP on Your Wired LAN
Proxy Mobile IP on access points works in conjunction with Mobile IP configured
on your network routers. For instructions on configuring Mobile IP on a router on
your network, refer to the Mobile IP chapter in 12.2 T New Features (Early
Deployment Releases). Click this link to browse to the Mobile IP chapter:

In addition, make sure you have accomplished the following items:
• Loaded the latest firmware onto all access points in your wireless network.
• Established an HTTP connection to the access point.
