L2TP over IPSec connection betweenthe ZyWALL USG and iPhoneiPhone 3G is now a very popular handheld device worldwide. It not only allows mobile users tosurf Internet, delivering push email, but also provides secure access to corporate resources bysupporting a variety of virtual private network (VPN) technologies. This document providesstep-by-step instructions for setting up a VPN connection between ZyWALL USG and aniPhone.ZyWALL USG configuration:1. Configure a user account for the iPhone use when connecting. Click theCONFIGURATION Object User/Group User page to create it. This user will bestored in “Local database”.
2. To build up the L2TP over IPSec connection, we have to create the IPSec rule first. ClickCONFIGURATION VPN IPSec VPN VPN Gateway page to create it.

Edit the default rule by filling in the following information: (click “Show Advanced Settings”first) VPN Gateway Name Gateway setting: select the local interface as My Address and set the peer side touse Dynamic Address (Peer Gateway Address) Pre-shared Key; this parameter will also be needed when configuring the iPhoneconnection.
4. Configure the Phase 1 proposal. There is a specific combination that is supported by theiPhone (depending on iOS version). Users can check the Appendix for more details.5. After the VPN gateway setting is done, click the CONFIGURATION VPN IPSec VPN VPN Connection page to create it. There is one pre-configured default rule for L2TPusage.
6. Edit the default rule by filling in the following information: (click “Show Advanced Settings”first) Connection Name Select the application scenario as Remote Access (Server Role) and select thepre-configured VPN Gateway rule.7. For L2TP over IPSec, we must use the Transport mode scenario, the VPN is configured asa Peer-to-Peer tunnel. Thus we have to select the WAN IP address as the Local Policy.
8. Configure the Phase 2 proposal. There is a specific combination that is supported by theiPhone (depending on iOS version). Users can check the Appendix for more details.9. After the VPN connection setting is done, click CONFIGURATION VPN L2TP VPN L2TP VPN page to create it. Select the VPN connection rule Assign the IP address pool Select the Allowed user

Click the L2TP tab and start to configure it. We need to fill in rule Description (e.g.iPhone L2TP), Server address (e.g. www.securityusg.com), Account and Password thatis configured in the USG L2TP allowed user setting.
3. The RSA SecurID option is not used. Secret must match the Pre-Shared Key from theIPSec Phase-1 rule of the ZyWALL USG. Click Save to save the L2TP configuration.4. Back to the VPN page, the tunnel can be activated via the on / off icon5. If the iPhone “Send all traffic” option is ON, user needs to create a policy route todo SNAT for iPhone to forward traffic to Internet via the L2TP tunnel.
