IPSec between Win 7 / iPhone and Linksys RV042 using NAT

Dear Community,

I have a problem with configuring the following network:

     Netzplan logisch.jpg

- laptop and iPhone should get access to the private LAN

- Speedport is connected to ADSL with an dynamic IP, but DynDns is activated

- Speedport uses NAT for forwarding ports 500 and 4500 to RV042

- RV042 should be the VPN-server

- LAN should be completely able to be accessed by the VPN-client (network printer, shared folders on windows, remote access ...)

- VPN connection should use IPSec for high security

- NAT-T must been used because Speedport only forwards UDP/TCP-ports and no protocols

I have some questions:

- how should I configure the IPSec on RV042?

- which VPN client software should I use ( NAT-T an Win7 64bit must be supported ) and how should it been configured?

This scenario with VPN-server behind a router should be a common one, but I can't realise it alone.

Normally I work as professional supporter for Cisco SMB (since 3 weeks), but this scenario is new for me and I don't know how to solve this problem.

Please help me. Thanks!

Sincerelly yours

Jan Weiring
