To use IM programs, a user would first launch a web browser and point it to the Sonicwall’s LAN IP address (http://192.168.168.168, or whatever that address may be). After supplying the username and password, the user will be authenticated and will then have rights to use this rule – in other words, they can launch those IM clients!
Building VPNs
With Sonic OS Enhanced, you will find all of the VPN capabilities of the previous firmware and more. Some of the new features are:
*The ability to define both a Primary VPN Gateway and a Secondary VPN Gateway for use in the event the primary is unavailable.
*For interoperability, the ability to define whether to use an IP Address, Domain Name, E- Mail Address, or the Sonicwall Identifier as a means of authenticating IKE negotiations.
*The ability to specify both the local protected network and the remote network, allowing a level of granularity that wasn’t before available.
