    Alrighty,

    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 172.16.29.0; remote is 172.16.20.0

    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) 22.33.44.55 netmask 255.255.255.255 no-xauth no-config-mode

    Step #2

    Create access lists for VPN Policy

    Access-list Pix-to-WRV54G permit ip 172.16.29.0 255.255.255.0 172.16.20.0 255.255.255.0

    Access-list outside_crypto_map_40 permit ip 172.16.29.0 255.255.255.0 172.16.20.0 255.255.255.0

    Step #3

    Create VPN Policy

    crypto map VPN_MULTIPURPOSE 40 ipsec_isakmp
    crypto map VPN_MULTIPURPOSE 40 set peer 22.33.44.55 <--- (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
    --------------------------------------------------------------------------
