Example 3 If you have a DHCP server on a Windows NT server and you want to use
this DHCP server to assign TCP/IP parameters to end devices on a remote
IP subnet, you need to set these filters to allow for the necessary IP
tunneling.
1. On the root access point, set these filters:
‰ On the IP Tunnels screen, check the Allow IP Multicast box.
‰ In the IP Tunnel Frame Type Filter table, configure DIX-IP-UDP
Ports to pass all frames.
2. On the access point at the endpoint of the IP tunnel, set this filter:
‰ In the IP Tunnel Frame Type Filter table, configure DIX-IP-UDP
Ports to pass all frames.
Example 4 If you have a Linux or Unix DHCP server and want to use this DHCP server
to assign TCP/IP parameters to end devices on a remote subnet, you
need to set this filter to allow for the necessary IP tunneling:
‰ In the IP Tunnel Frame Type Filter table, configure DIX-IP-UDP Port
to pass all frames.
