Configuring Local and Local,L3 DHCP Scopes

You can configure Local and Local,L3 DHCP scopes by using the AOS-W Instant UI or CLI.

l Local — In this mode, the Virtual Controller acts as both the DHCP Server and the default gateway. The

configured subnet and the corresponding DHCP scope are independent of subnets configured in other OAW-IAP

clusters. The Virtual Controller assigns an IP address from a local subnet and forwards traffic to both corporate

and non-corporate destinations. The network address is translated appropriately and the packet is forwarded

through the IPSec tunnel or through the uplink. This DHCP assignment mode is used for the NAT forwarding

mode.

l Local, L3— In this mode, the Virtual Controller acts as a DHCP server and the gateway, and assigns an IP

address from the local subnet. The OAW-IAP routes the packets sent by clients on its uplink. This mode does not

provide corporate access through the IPsec tunnel. This DHCP assignment mode is used with the L3 forwarding

mode.

In the AOS-W Instant UI

Select any of the following options:

l Local— On selecting Local, the DHCP server for local branch network is used for

keeping the scope of the subnet local to the OAW-IAP. In the NAT mode, the traffic

is forwarded through the IPSec tunnel or the uplink.

l Local, L3—On selecting Local, L3, the Virtual Controller acts as a DHCP server and

gateway. In this mode, the OAW-IAP routes the packets sent by clients and also

adds a route on the Switch, after the VPN tunnel is set up during the registration of

the subnet.
