    do you have "ip local pool" in your config? namely "address-pool"

    is it possible you did not write your config after the upgrade, and lost
    these commands?

    After upgrading 3620 with an 8 modem card from 12.0(7)XK2 to 12.2(17a)
    ppp negotiation is failing at ipcp. Tested
    using w98 and 2000 DUN.

    Here's the relevant part of the config.

    bug CSCdk61031 looks related but fixed long ago.

  3. ^^^^^^^^^^^^^^

    This means that IP is not configured, so of course IPCP will fail.

    You probably meant to configure "ip unnumbered ethernet 0"

    This can not have been caused by the upgrade, it is a misconfiguration that
    would fail in any version of IOS..

    Ah ha! That makes sense, however, reportedly people were connecting
    under this config prior to the upgrade.
    Anyway I added an ip unnumbered fastethernet and it's at least
    initiaiting ipcp, but.....

    initial rejection.

  5. re: Cannot satisfy pool request

    I see in some documentation the ip dhcp-server command which I don't
    have configured. However I don't see it under the 12.2 command reference
    and I'm wondering if it's deprecated and how interacts with the ip
    helper-address command. Does it just affect local dhcp requests, i.e.
    from dial-in clients.
