1.4.3 GRE Tunnel

GRE Tunneling capability provides the ability to create a GRE tunnel from a switch to a switch/router at the
remote end through an IP backbone. The primary functionality is to provide IP services (from the remote end /
core of the network) to the MUs on particular WLANs that are mapped to the GRE tunnels. The data arriving
from a MU associated a particular WLAN would be sent across to that GRE endpoint.
This functionality inWS5000 v2.1 is based on v1.4.3 when GRE tunneling capability was first introduced. V2.1
will also provide the capability to enable up to 4 GRE tunnels and provide the necessary WLAN mapping and
other required configuration parameters (including Remote IP Address, Time To Live and Keep Alive).
Common tunneling protocols include:
• Generic Routing Encapsulation (GRE)
• Layer2 Tunneling (L2TP)
• IPSec VPN
• Multi Protocol Label Switching (MPLS) VPN
• IP over IP

1.4.4 Dual DHCP Server

Currently the DHCP server is used along with the VPN server to serve public addresses to the wireless clients.
It can be enabled only on one NIC at one time. It is required that the DHPC server should be able to serve IP
addresses on both the interfaces, and should be able to serve IP addresses from different pool of addresses
on both interfaces.
Since the DHCP server may be used directly with WPA/WPA2 (without VPN), the requirement is that the DHCP
configuration should be available, even when VPN is not enabled.
Also, there is a requirement to restrict serving of the IP-addresses only to the primary (native) VLAN. So, a new
configuration is provided to meet this requirement.
