This section describes how to set up PPP over Ethernet (PPPoE).
No kernel configuration is necessary for PPPoE any longer. If the necessary netgraph support is not built into the kernel, it will be dynamically loaded by ppp.
Here is an example of a working
ppp.conf
:
xl1
# replace xl1 with your Ethernet device
set authname YOURLOGINNAME
set authkey YOURPASSWORD
set dial
set login
add default HISADDRAdd the following to your
/etc/rc.conf
file:
Sometimes it will be necessary to use a service tag to establish your connection. Service tags are used to distinguish between different PPPoE servers attached to a given network.
You should have been given any required service tag information in the documentation provided by your ISP. If you cannot locate it there, ask your ISP's tech support personnel.
As a last resort, you could try the method suggested by the Roaring Penguin PPPoE program which can be found in the Ports Collection. Bear in mind however, this may de-program your modem and render it useless, so think twice before doing it. Simply install the program shipped with the modem by your provider. Then, access the menu from the program. The name of your profile should be listed there. It is usually ISP.
The profile name (service tag) will be used in the PPPoE
configuration entry in ppp.conf
as the
provider part of the set device
command
(see the ppp(8) manual page for full details). It should
look like this:
xl1
:ISP
Do not forget to change xl1
to the proper device for your Ethernet card.
Do not forget to change ISP
to the profile you have just found above.

This modem does not follow RFC 2516 (A Method for transmitting PPP over Ethernet (PPPoE), written by L. Mamakos, K. Lidl, J. Evarts, D. Carrel, D. Simone, and R. Wheeler). Instead, different packet type codes have been used for the Ethernet frames. Please complain to 3Com if you think it should comply with the PPPoE specification.
In order to make FreeBSD capable of communicating with
this device, a sysctl must be set. This can be done
automatically at boot time by updating
/etc/sysctl.conf
:
or can be done immediately with the command:
#
sysctl net.graph.nonstandard_pppoe=1
Unfortunately, because this is a system-wide setting, it is not possible to talk to a normal PPPoE client or server and a 3Com® HomeConnect® ADSL Modem at the same time.
