Chapter 14 Configuring Proxy Mobile IP
Configuring Proxy Mobile IP
• 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 to browse to this article:

• Proxy Mobile IP does not support VLANs.
• If you disable proxy Mobile IP on your access point, the entire proxy Mobile IP configuration is
cleared. To disable proxy Mobile IP without clearing the configuration, use the ip proxy-mobile
pause command.
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

point:

Designate the access points that serve as the authoritative
access points (the access points with which this access point
compares its subnet table).
Note You should specify at least two access points as AAPs
in case one AAP fails. If you designate only one AAP
and it goes offline, you lose all the information in the
subnet map table.

an IP range.
• Enter the security parameter index.
• Enter a key for the security parameter. Specify whether the
key contains hexadecimal or ASCII characters. If you
choose hexadecimal, the key must contain 32 characters. If
you choose ASCII, the key can contain up to 16 characters
with no minimum length.
