Use the settings to configure custom PPP interfaces.
Under , you can add a new or edit an existing PPP interface.
The configuration dialog allows you to configure the following elements:
| Input field | Description |
|---|---|
| I/0 | A slider switch indicates whether the PPP interface is active (I) or inactive (0). Click the slider switch to change the status of the PPP interface link. New PPP interfaces are activated by default. |
| Master Interface | From the drop-down list, select the Ethernet, VLAN or bridge interface that the PPP interface is associated with. |
| LCP Echo Interval | Specify at which interval (in seconds) your LANCOM R&S®Unified Firewall sends an echo request to the peer by entering an integer value from 1 to 1800. |
| LCP Echo Failure | Specify the number of LCP echo failures after which the peer is considered dead by entering an integer value from 0 to 64. If you enter 0, failures are ignored. |
| MTU | Set the maximum size of each packet (in bytes). The maximum transmission unit can be any integer from 64 to 16384. |
| MRU | Specify the maximum receive unit by entering an integer value from 128 to 16384. |
The buttons at the bottom right of the editor panel depend on whether you add a new PPP interface or edit an existing one. For a newly configured PPP interface, click Create to add it to the list of available PPP interfaces or Cancel to discard your changes.
