    The openswan list is probably the best place to ask this kind of
    question, since it's dedicated to ipsec and openswan questions. A bunch
    of folks on that list seem to be pretty familiar with debian as well. I
    may be able to offer a little advice, but those guys are the real gurus.

    are you running KLIPS, or native IPsec? If you are not running KLIPS,
    you dont need (and cannot use) this line. What kernels are you using?
    What is the output of ipsec verify & ipsec auto --status on both hosts?
    You say that the client is having problems communicating with one host
    on the remote LAN. Can it communicate with any others? Can the gateway
    ping the client?
