240 | IAP-VPN Deployment Dell Networking W-Series Instant 6.4.3.1-4.2.0.0 | User Guide
l Branches—The number of IAP-VPN branches that can be terminated on a given controller platform.
l Routes—The number of L3 routes supported on the controller.
l L3 mode and NAT mode users—The number of trusted users supported on the controller. There is no
scale impact on the controller. They are limited only by the number of clients supported per W-IAP.
l L2 mode users—The number of L2 mode users are limited to 128000 for W-7220/W-7240 and 64000
across all platforms.
IAP-VPN Forwarding Modes
The forwarding modes determine whether the DHCP server and default gateway for clients reside in the
branch or at the datacenter. These modes do not determine the firewall processing or traffic forwarding
behavior. The Virtual Controller enables different DHCP pools (various assignment modes) in addition to
allocating IP subnets for each branch.
The Virtual Controller allows different modes of forwarding traffic from the clients on a VLAN based on the
DHCP scope configured on the W-IAP.
For the IAP-VPN deployments, the following forwarding modes are supported:
l Local mode
l L2 Switching mode
l L3 routing mode
The DHCP scopes associated with these forwarding modes are described in the following sections.
Ensure that VLAN 1 is not configured for any of the DHCP scopes as it is reserved for a different purpose.
Local Mode
In this mode, the W-IAP cluster at that branch has a local subnet and the master W-IAP of the cluster acts as the
DHCP server and gateway for clients. The local mode provides access to the corporate network using the inner
IP of the IPsec tunnel. The network address for traffic destined to the corporate network is translated at the
source with the inner IP of the IPSec tunnel and is forwarded through the IPsec tunnel. The traffic destined to
the non-corporate network is translated using the IP address of the W-IAP and is forwarded through the
uplink.
When the local mode is used for forwarding client traffic, hosts on the corporate network cannot establish
connections to the clients on the W-IAP, because the source address of the clients is translated.
Local L2 Mode
In this mode, the W-IAP cluster at that branch has a local subnet and the master W-IAP of the cluster acts as the
DHCP server. The default gateway is located outside the W-IAP and the network address for the client traffic is
not translated at source. In the local l2 mode, access to the corporate network is supported only in a single W-
IAP cluster. The traffic to the non-corporate network is locally bridged.
Local L3 Mode
In this mode, the network address for traffic destined to the corporate network is translated at the source with
the inner IP of the IPSec tunnel and is forwarded through the IPsec tunnel. The traffic destined to the non-
corporate network is routed.
