I recently purchased a Cisco RV180W VPN router and would like to enable the VPN (specifically IPSec) capabilities so that I can connect via my Android 4.0 (Samsung Galaxy S3) phone. I need step by step instructions (I'm quite unfamiliar with Cisco routers) to configure both the router and my Android phone to do this. I've actually been able to configure the RV180W to work with PPTP (and connect via my phone with PPTP), but would prefer to use IPSec. Please help. Thanks!
