DHCP Configuration

This chapter provides the following information:

l

Configuring DHCP Scopes on page 211

l

Configuring the Default DHCP Scope for Client IP Assignment on page 218

Configuring DHCP Scopes

The VC supports different modes of Dynamic Host Configuration Protocol (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 243

.

When using a local DHCP scope in an IAP cluster, ensure that the VLANs configured for this DHCP scope is
allowed in the uplink switch.

In a single 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 IAP E0 port is connected.

This section describes the following procedures:

Configuring Local DHCP Scopes

You can configure Local; Local, L2; and Local, L3 DHCP scopes through the Instant UI or the CLI.

l

Local

—In this mode, the VC acts as both the DHCP server and the default gateway. The configured subnet

and the corresponding DHCP scope are independent of the subnets configured in other IAP clusters. The VC
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 Networks Address
Translation (NAT) forwarding mode.

l

Local, L2

—In this mode, the VC acts as a DHCP server and the gateway located outside the IAP.

l

Local, L3

—This DHCP assignment mode is used with the L3 forwarding mode. In this mode, the VC acts as

a DHCP server and the gateway, and assigns an IP address from the local subnet. The 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 a 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.

3. Based on the type of DHCP scope selected, configure the following parameters:
