sppptun

Defines sppptun as the name of the serial device.

plugin pppoe.so

Instructs pppd to load the pppoe.so shared object.

connect "/usr/lib/inet/pppoec hme0"

Runs pppoec and designates hme0 as the interface for the PPPoE tunnel and PPP link.

noccp

Turns off CCP compression on the link.

Note -

If they use any compression algorithms at all, many ISPs use only proprietary compression algorithms. Turning off the publicly available CCP algorithm saves negotiation time and avoids very occasional interoperability problems.

noauth

Stops pppd from demanding authentication credentials from the access server. Most ISPs do not provide authentication credentials to customers.

user Red

Sets the name Red as the user name for the client, required for PAP authentication by the access server.

password redsecret

Defines redsecret as the password to be provided to the access server for PAP authentication.

noipdefault

Assigns 0.0.0.0 as the initial IP address.

defaultroute

Tells pppd to install a default IPv4 route after IPCP negotiation. You should include defaultroute in /etc/ppp/peers/peer-name when the link is the system's link to the Internet, which is true for a PPPoE client.
