Dell Networking W-Series Instant 6.4.3.1-4.2.0.0 | User Guide DHCP Configuration | 215
Chapter 14
DHCP Configuration
This chapter provides the following information:
l Configuring DHCP Scopes on page 215
l Configuring the Default DHCP Scope for Client IP Assignment on page 222
Configuring DHCP Scopes
The virtual controller supports different modes of DHCP address assignment. With each DHCP address
assignment mode, various client traffic forwarding modes are associated. For more information on client traffic
forwarding modes for IAP-VPN, see IAP-VPN Forwarding Modes on page 240.
When using a local DHCP scope in a W-IAP cluster, ensure that the VLANs configured for this DHCP scope is
allowed in the uplink switch.
In a single W-IAP network, when using a client DHCP scope for wired clients, ensure that client VLAN is not
added in the allowed VLAN list for the port to which the W-IAP E0 port is connected.
This section describes the following procedures:
l Configuring Local DHCP Scopes on page 215
l Configuring Distributed DHCP Scopes on page 217
l Configuring Centralized DHCP Scopes on page 220
Configuring Local DHCP Scopes
You can configure Local, Local, L2, and Local, L3 DHCP scopes through the 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 W-
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 in
the NAT forwarding mode.
l Local, L2—In this mode, the Virtual Controller acts as a DHCP server and the gateway located outside the
W-IAP.
l Local, L3— This DHCP assignment mode is used with the L3 forwarding mode. In this mode, the Virtual
Controller acts as a DHCP server and the gateway, and assigns an IP address from the local subnet. The W-
IAP routes the packets sent by clients on its uplink. The Local, L3 subnets can access corporate network
through the IPsec tunnel. The network address for all client traffic, which is generated in the Local, L3
subnets and destined to the corporate network, is translated at the source with the tunnel inner IP.
However, if corporate access to Local, L3 is not required, you can configure ACL rules to deny access.
In the Instant UI
To configure a Local or Local, L3 DHCP scope:
1. Click More > DHCP Server. The DHCP Server window is displayed.
2. To configure a Local, Local, L2 or Local, L3 DHCP scopes, click New under Local DHCP Scopes. The New
DHCP Scope window is displayed.
