<h1 class="topictitle1">Remote IP address pools</h1>
|
||
|
|
<div><p>The system can use remote IP address pools for any answering or
|
||
|
|
stopping point-to-point connection profile that is used with multiple incoming
|
||
|
|
connections.</p>
|
||
|
|
<p>This includes L2TP and line pools with a maximum number of connections
|
||
|
|
greater than one. This function allows the system to assign a unique remote
|
||
|
|
IP address to each incoming connection.</p>
|
||
|
|
<p>The first system to connect receives the IP address defined in the Starting
|
||
|
|
IP address field. If that IP address is already in use, the next IP address
|
||
|
|
within the range is given out. For example, assume that the Starting IP address
|
||
|
|
is 10.1.1.1 and the Number of IP addresses is defined as 5. The IP addresses
|
||
|
|
within the remote IP address pool will be 10.1.1.1, 10.1.1.2, 10.1.1.3, 10.1.1.4,
|
||
|
|
and 10.1.1.5. The subnet mask defined for the remote IP address pool addresses
|
||
|
|
will always be 255.255.255.255.</p>
|
||
|
|
<p>These restrictions apply when using remote IP address pools: </p>
|
||
|
|
<ul><li>More than one connection profile can specify the same address pool. However,
|
||
|
|
when all the IP addresses in the pool are used, any subsequent connection
|
||
|
|
request is refused until another connection ends and an IP address becomes
|
||
|
|
available.</li>
|
||
|
|
<li>To allocate specific IP addresses to some remote systems while allowing
|
||
|
|
other incoming systems to use an IP address from the pool, follow these steps: <ol><li>Enable Remote system authentication from the <span class="uicontrol">Authentication</span> tab,
|
||
|
|
so the user name of the remote system can be learned.</li>
|
||
|
|
<li>Define a remote IP address pool for all incoming connection requests that
|
||
|
|
do not require a specific IP address.</li>
|
||
|
|
<li>Define remote IP addresses for specific users by checking <span class="uicontrol">Define
|
||
|
|
additional IP addresses based on remote system's user ID</span>, and
|
||
|
|
then clicking <span class="uicontrol">IP addresses defined by User Name</span>.</li>
|
||
|
|
</ol>
|
||
|
|
<p>When the remote user connects, the iSeries™ server determines whether a specific
|
||
|
|
IP address is defined for this user. In this case, the IP address is given
|
||
|
|
to the remote system; otherwise, an IP address from the remote IP address
|
||
|
|
pool is returned.</p>
|
||
|
