    I have given the 2851 an IP address of 10.0.0.81/16 pm G0/0 and an IP address of 192.168.0.1/24 on L0

    Re: cannot get terminal server config to work

    Hi,

     

    I edited out all the show commands you posted as they were unneeded and made the post way too long.  You issues is you are using 2000 plus the TTY line number in your ip host entries and it should be 2000 plus the router assigned line number which starts at 66 on this platform.

    Change your config to be,

     

    ip host R1 2066 192.168.0.1

    etc ..

    and it might solve some issues if you prevent access to the exec of the router by the remote device. Add "no exec" to your line 1/0 1/31 config section.

    That was it.  I should have seen it as the sh line command put it right there in front of me, however I was frantic (panic) and searched google for examples.  The problem is the examples are from 10-12 years ago and reflected a 2511 or 2600 series router with older software and the NM-16A



    Thanks MHughes
