How do I tell when the site to site VPN is established?

    I'm trying to establish a site to site, or LAN to LAN VPN, which should
    allow full access between LAN "A" and LAN "B". Once I have the config set
    up the way it should be, does the VPN tunnel just "automagically" appear?
    Do I have to do "something" to make it happen? Do I have to reboot the ASA?
    How do I tell if it is working?

    I'm doing all of the config using remote access (via ASDM) to the two ASA
    5505's in question, so I can't see the "VPN" light on the front of the unit,
    nor do I have access to try a ping from a machine on one LAN to a machine on
    the other LAN. The only pinging I can try is from the ping function in

    Should the VPN "counter" on the main screen of ASDM change from 0 to 1 as
    soon as I get the config correct, or does data matching the ACLs have to
    flow before it establishes the tunnel?

    I know these are stupid questions, but I really appreciate any help.

    Do you have access to SSH or telnet into the ASA's? If so you can
    probably do something like:

    sh crypto isakmp sa

    sh crypto ipsec sa

    I can't say I have much experience with the graphical ASDM so I am not
    sure. From command line the show crypto area is where you will want
    to be to find most of your relevant info assuming the ASAs even have
    those commands.
