    We connect to other branch offices using a Cisco VPN concentrator
    (Cisco Systems, Inc./VPN 3000 Concentrator Version 4.7.2.C Nov 30 2005
    00:19:31). I am having trouble with LAN-2-LAN connectivity with a PIX
    (I don't know the version or particulars on that device). The tunnel
    can be established but is disconnected every 15-30 seconds, after which
    time it comes back up on its own. No traffic, though, has been able to
    pass through that tunnel. I maintain no NATs that would affect any of
    the addresses for this tunnel. The other party, however, is NAT-ing
    their privately addressed host to a public address. I include this
    here because I found a German forum that referenced my exact error
    message and that spoke of NATs and nat traversal. The errors that I am
    seeing in my concentrator's log are as follow:

    The public IP address is always the peer address of the PIX. Thanks in
    advance. Elinor
