Outgoing Connections - Lantronix SCS Reference Manual

Basic Remote Networking
Keep in mind that PPPdetect and SLIPdetect will only need to be disabled on ports that have PPP
and/or SLIP enabled.
Local>> DEFINE PORT 2 PPPDETECT DISABLED
Local>> DEFINE PORT 2 SLIPDETECT DISABLED
In order for SLIP users to perform authentication, SLIPdetect must be disabled. SLIP users will
only be able to authenticate incoming connections while the port is in character mode; once the
port is running SLIP (for example, if the port is dedicated to SLIP using the Define Ports SLIP
Dedicated command), authentication cannot be performed.
If the port is configured to automatically run PPP and you'd like to use CHAP or PAP to obtain
a username and password from the incoming caller, enable remote CHAP and/or PAP
authentication on the desired port.
Local>> DEFINE PORT 2 PPP CHAP REMOTE
Local>> DEFINE PORT 2 PPP PAP REMOTE
CHAP and PAP may both be enabled on the same port.
Note:
If incoming connections will be entering usernames to start a custom site, ensure that the site has
a local password. Callers will be required to enter this password in order to start the site.
Local>> DEFINE SITE irvine AUTHENTICATION LOCAL "gorilla"
Configure any databases that will be used for authentication and add the appropriate usernames
and passwords. See Chapter 11, Security, for configuration instructions.

4.6 Outgoing Connections

The SCS does not support outgoing remote node connections.
Note:
When the SCS receives a packet, it consults its routing table to determine the best route to the packet's
destination. If the specified route points to a site, a connection to the site may be initiated. The connection
will be subject to any restrictions defined for the site, such as a startup filter or time of day restrictions.
When a connection to the remote router is initiated, a limited number of packets will be buffered until the
connection is formed. When the connection is successful, the packets will be sent.
To restrict outgoing connections, see Chapter 11, Security.
Note:
The SCS can form outgoing connections where it accepts an IP address and a nameserver from the remote
PPP site. Enable this feature with the Set/Define IP IPaddress Dynamic command. Connections which
require these settings include sites which dial up an ISP, where the ISP then assigns the SCS a nameserver
and IP address. For more information, see Dialing Out to an ISP on page 6-5.
To configure the SCS for outgoing connections, you must set up sites. The following sections describe how
the SCS handles these connections.
