    I've been goofing around this evening and have configured vpn tunnels from my Pix 501 to a WRV54G, RV042, and a WRVS4400N. Tunnels are up and running fine. The down side is the vpn on the pix is software based, so the ping times increase with each tunnel I make, but it's an exercise in just seeing if I can do it. Anyway, below are the steps to take. FOLLOW THIS "LINE BY LINE" AND IT SHOULD WORK FOR YOU

    Be sure to be in “global configuration mode” before entering the following commands on your PIX as shown below:

    NOTE: Local lan ip in this example is; remote is

    Step #1

    Create ISAKMP Policy (Phase II)

    isakmp policy 40 authentication pre-share
    Isakmp policy 40 encryption 3des
    Isakmp policy 40 hash sha
    Isakmp policy 40 group 2 (put a space between "group" and "2" for the policy)
    Isakmp policy 40 lifetime 28800
    Isakmp key (key goes here) netmask no-xauth no-config-mode

    Step #2

    Create access lists for VPN Policy

    Access-list Pix-to-WRV54G permit ip

    Access-list outside_crypto_map_40 permit ip

    Step #3

    Create VPN Policy

    crypto map VPN_MULTIPURPOSE 40 ipsec_isakmp
    crypto map VPN_MULTIPURPOSE 40 set peer <--- (WAN IP of remote network)
    crypto map VPN_MULTIPURPOSE 40 match address Pix-to-WRV54G
    crypto map VPN_MULTIPURPOSE 40 set transform-set esp-3des-sha
    crypto map VPN_MULTIPURPOSE 40set pfs group2

    If you are unsure on how to set up a gateway vpn tunnel on your router, check out the tutorial section where I've posted a few videos showing how to connect linksys routers together via a vpn tunnel.
