The correct way would be to fully add the 10.0.0.10/32 network on the tunnel, thus allowing just that remote endpoint. Depending on the NATing, Inter Zone the SonicWall can potentially see the source IP, that the source is from a VPN IP, and the remote admin would need to make allow rule for that traffic to be allowed. SonicWALL security appliances can also drive VPN traffic through the NAT policy and zone policy, since VPNs are now logically grouped into their own VPN zone. How Zones Work An easy way to visualize how security zones work is to imagine a large new building, with several rooms inside the building, and a group of new employees that do not know Services: VPN using iPad/iPhone/iPod Touch (using L2TP option on the SonicWall appliance) Feature/Application: This document explains how to configure the iPad/iPhone/iPod Touch (we will refer to the name iPad for the rest of this document) L2TP Client access to the SonicWall WAN GroupVPN SA using the built-in L2TP Server.
