Enabling Proxy ARP for WLANs Mapped to Tunnels
A GRE tunnel does not carry non-IP traffic such as Address Resolution
Protocol (ARP). Therefore, a Wireless Edge Services xl Module that maps a
WLAN to a tunnel must be able to respond to ARP requests on behalf of
wireless stations.
Proxy ARP is enabled by default. If it has been disabled, complete these steps
to re-enable it:
1. Select Network Setup > WLAN Setup > Configuration.
2. Click the
Global Settings
button. The
Global WLAN Settings
screen is
displayed.
