    we were going to use originally works when we place a computer on its own
    line without a firewall. I just transpose the group and group password
    fields from the client to the vpngroup command, and the user/password that
    comes up during connect, to the username command.

    Sadly no.

    This turned out to be an issue with our modem. It used MAC address's to
    assign static IPs, so when I transfered the static to the firewall, the
    modem did not like that. A modem reset fixed that issue. However, when I
    use the configuration I have shown above, I can only ping address's from
    both the firewall and PC. I cannot ping names, such as www.google.ca (which
    I use as my test page simply cause i know the address for it
    (66.102.7.104)). When I try to ping a name from the PC, it comes back as no
    such name exists, and I can't seem to make the firewall ping any name,
    possibly due to the way the ping command on the firewall works.

    Anyway, when I enable the VPN client, all access, including those pings,
    stops working. However, according to the little led on the front, I am
    connected to the VPN. I don't have access to anything on their end however.

    Well, there is the needed information. I hope it helps.
