# Add point-to-point protocol clients to Single Engine interfaces

You can use PPPoE or PPPoA clients to connect the Engine to an external ADSL modem without configuring routing and NAT settings on the ADSL modem.

##

Point-to-point protocol over Ethernet (PPPoE) and point-to-point protocol over ATM (PPPoA) clients on the Engine simplify the installation of an appliance when PPPoE or PPPoA is used by the network link connected to the interface. Activating the PPPoE or PPPoA client on the Engine allows you to connect the Engine to an external ADSL modem in transparent bridge mode. You must also activate the PPPoE or PPPoA client on the Engine if you have a specific appliance that has an ADSL port and the ISP for the ADSL connection requires PPPoE or PPPoA.
Note:

- The PPPoE client is supported for both dynamic IPv4 addresses and dynamic IPv6 addresses on single engines.
- For a SMC managed single engine, the same PPP settings are shared if the interface has both IPv4 and IPv6 PPPoE configured.
- The PPPoE interface supports working in conjunction with single IP HA, route probing, and netlinks.

4. If you are creating a Engine, or if you want to change the roles the different interfaces have in the configuration, select system communication roles for engine interfaces.
5. Otherwise, click Save and Refresh.
