Some of the new features

NAT

Next to traditional L2 WLAN switching and L3 routed functions, the updated release includes support for NAT. This will allow for instance a wireless guest IP subnet to be address translated to an internet port connected to the Unified controller.

ASPF

Application Specific Packet Filter is a firewall function which has been added. The ASPF firewall supports TCP, UDP and several other application layer protocols.

AP-Groups

An MSM-like feature, which allows pushing AP Configuration to an AP-Group, as opposed to pushing it to individual APs.

Policy-based Forwarding

This feature provides the network admin control over which traffic is forwarded centrally by the controller or locally by the AP. The admin can define ACLs which match source /destination information. These ACLs can be referenced as local or central forwarding rules.

Staged Firmware Upgrades

Enables the admin control over which APs will be updated to the new firmware release. This makes it possible to upgrade a limited number of APs at a time, reducing the downtime of the wireless network as a result of firmware updates.

Distributed Web-Authentication

Provides the ability to have central Web Authentication first, but provide local data forwarding (on the AP) for the authenticated users.

Guest VIP Channel

Transports guest traffic over an IACTP tunnel to a controller on a DMZ. This provides clean isolation of the guest traffic form the unified controller IP point of view.

VLAN Pool

Defines a range of VLANS, can be used for load-balancing users. When the radius server assigns users to the VLAN pool, users will be distributed over the VLANs in the VLAN Pool.

There are many other new features, so this is just a select overview. I hope to have some updated articles with sample configs soon.
