    We have been using a PIX 501 for a couple of years now to access a
    local network with Cisco VPN software client. However we now need
    access from another site with multiple users so I decided to buy two
    ASA 5505 UL bundle to do the job. First i tried to just hook up the
    new ASA at the remote site and connect to the PIX 501 with easy vpn.
    In went fine. I configured the new ASA right from the box with the old
    vpn profile settings and it worked right away. But as we also need the
    remote site to be accessed from the main site (PIX side) i tried to
    enable "network extension mode" but then the tunnel didnt work
    anymore. it connects but no traffic is coming through. I set it back
    to normal mode (only client) and it worked again.

    Is there anything else I need to do to be able to use network
    extension mode than just enabling it in ASDM ?

    The samt thing happens when using two ASA 5505 the same way.

    Software versions are:

    PIX: 6.3

    ASA 5505: 7.2.1 (used to be 7.2.2 but I had to downgrade because of a
    bug in 7.2.2 - vpnclient fails after reboot)

    Sorry for sending a reply to my own post but heres an update:

    According to the log heres what happens when pinging the remote ip using only "client mode":

    6 Jun 17 2007 05:23:05 302020 Built ICMP
    connection for faddr gaddr laddr

    And heres what happens when pinging the remote ip using
    network extension mode:

    302020 Built ICMP connection for faddr gaddr laddr gaddr laddr

    It seemes as the network extension mode does not set the correct
    gateway (this case which is the IP the vpn client get from
    the PIX vpn pool).

    Any ideas ?

    Another bug ?
