Cannot SSH to pix 501 outside interface while using EasyVPN in network-extension-mode

    I have several pix 501's connected to a 3005 concentrator, setup with
    the following config. I cannot get management access to the outside
    interface using SSH or HTTPS. I am trying to access from my home
    cable modem, I can successfully SSH the router that is in front of the
    PIX. All Internet traffic from behind the pix 501 needs to continue
    to go through the VPN tunnel for filtering. Everything currently
    works the way I need it to, I cannot manage the outside interface.
    Any help would be appreciated.

    If you are not doing split tunneling, then it will not be possible
    (doesn't look like you are). Check the group config on the concentrator
    to enable it.

  3. since you allready have this, just point to the inside IP, instead.
    That way it is all secured in the tunnel aswell.

    Just point the services to inside:
    http someIP inside
    ssh someIP inside
    pdm location someIP inside

    Also you can do this with AAA, syslog, telnet etc.

    Thanks for the feedback. I need to have all traffic (including
    internet) to go through the VPN tunnel because I have web filtering at
    Headquarters (compliance reasons). I must have "tunnel everything"
    checked on the concentrator. I have found myself in the situtuation
    where a config was made on a pix 501 (while onsite) that was not
    written to memory (totally my fault). The power went out a couple
    weeks late, the 501 reboots to the original config. Then I spend the
    next day driving for 8 hours. Is there another way to divert all
    Internet traffic throught the VPN tunnel without having the "tunnel
    everything" checked?
