Cisco 851 VPN Setup

Does anyone have any advice about setting up an 851 to allow remote users VPN access to the network? Everything I read about the 851 was it was “easy” to setup VPN’s, now I’m not so sure. I prefer to do it via Cisco SDM GUI.

I guess I’m not sure what basic architecture to use, how to config etc.

I have downloaded the Cisco VPN client software and will need to config that also.

Setup is with a static IP on the WAN port via cable modem.
Thanks,
