Ensuring That the Remote Endpoint Can Forward
Traffic
A Wireless Edge Services xl Module GRE tunnel has two endpoints:
one that receives traffic from a WLAN and forwards it over the tunnel,
or (for return traffic) receives traffic over the tunnel and forwards it to
the WLAN
The Wireless Edge Services xl Module plays this role.
one that receives traffic over the tunnel and forwards it onto the destina-
tion network (a LAN or the Internet), or (for return traffic) receives traffic
from the destination network and forwards it over the tunnel
Make sure that the remote endpoint knows the proper routes. Remember:
it is the wireless station’s default router. The remote endpoint should also
implement DHCP services or DHCP relay on the tunnel interface.
