|

|
<div><p>Depending on your system and network configuration, a user who
|
|||
|
|
starts a SLIP connection might be able to access another system in your network
|
|||
|
|
without signing on to your system.</p>
|
|||
|
|
<p>For example, a user could establish a SLIP connection to your system. Then
|
|||
|
|
the user could establish an FTP connection to another system in your network
|
|||
|
|
that does not allow dial-in. </p>
|
|||
|
|
<p>You can prevent a SLIP user from accessing other systems in your network
|
|||
|
|
by specifying N (No) for the Allow IP datagram forwarding field in the configuration
|
|||
|
|
profile. This prevents a user from accessing your network before the user
|
|||
|
|
logs on to your system. However, after the user has successfully logged on
|
|||
|
|
to your system, the datagram forwarding value has no effect. It does not limit
|
|||
|
|
the user’s ability to use a TCP/IP application on your iSeries™ system (such as FTP or TELNET),
|
|||
|
|
to establish a connection with another system in your network.</p>
