Configuring PPP access over a serial port

Use the point-to-point (PPP) access method if you do not have Ethernet access.

NOTE:

Use PPP over the serial port for remote access to the RSA.

To configure PPP over the serial port:

1In the navigation pane, select Network Interfaces under the ASM Control heading.

2Scroll down to the PPP over Serial Port selection (see Figure 19, PPP over Serial Port, on page 44).

Figure 19: PPP over Serial Port

3In the Interface field [default: Disabled]: Select Enabled to use PPP over the serial port.

4In the Local IP address field [default: 10.4.0.1]: Type the local IP address for the PPP interface on the RSA. The IP address must consist of four integers ranging from 0 to 255, separated by periods, no spaces or consecutive periods.

5In the Remote IP address field [default: 10.4.0.2]: Type the remote IP address that the RSA assigns to a remote user. The remote IP address must consist of four integers ranging from 0 to 255, separated by periods, no spaces or consecutive periods.

6In the Subnet mask field [default: 255.255.255.254]: Type the subnet mask for the RSA. The subnet mask must consist of four integers ranging from 0 to 255, separated by periods, no spaces or consecutive periods.

7In the Authentication field [default: CHAP then PAP]: Select the type of authentication protocol that will be negotiated for a PPP connection:

•CHAP then PAP: When using this setting, authentication tries using CHAP first. If CHAP was unsuccessful, then PAP is tried as a secondary protocol.

•PAP Only: When using this setting, a two-way handshake procedure is used to validate the identity of the incoming caller. PAP must be used if a plain text password must be available to simulate a login at a remote host.

•CHAP Only: When using this setting, a three-way handshake procedure is used to validate the identity of the incoming caller and any time after the call is established. CHAP protects against playback and trial-and-error attacks.

8Click Save to store the changes.

9You must restart the ASM to activate the Network Protocols changes. To restart ASM, select Restart ASM under the ASM Control heading in the navigation pane.
