    Hello,

    Our company has Cisco 3030 VPN Concentrator's which have been in place
    for about 2 years now. The issue we are running into is if any user
    is NOT behind a NAT device they will be able to connect but will not
    be able to receive any traffic through the Concentrator. This only
    happens if they connect via the Ethernet 2 (External) interface. They
    can make a successful connection and pass data through when connecting
    via the Concentrator's Public interface (Internet). We have a TAC
    case opened with Cisco but they haven't come back with anything yet.
    Anyone out there having this type of issue or have any advice on what
    to verify/check on the Concentrator as well as the client's config.

    Thanks,

    Brian

    This isn't for internal folks connecting to your own vpn concentrator
    is it? Sounds like a familiar problem that requires some special
    configurations if this is the case (related to routing back to the
    internal network through the public interface). If its strictly
    external users, then not really sure.

    You could always ask your users to Drive Golf Carts to the buildings
    they are trying to connect to. This would cut down on network
    bandwidth as well as erase your need for a VPN Concentrator?
