Setting a PPPoEd Server This HOWTO is for setting a FreeBSD ppp over Ethernet server with pppoed

1. Compile kernel with this options: options NETGRAPH options NETGRAPH_PPPOE options NETGRAPH_SOCKET

2. Edit /etc/rc.conf, add: pppoed_enable="YES" pppoed_flags="-d -P /var/run/pppoed.pid -a "server" -l "default" " pppoed_interface="fxp1"

3. /etc/ppp/ppp.conf default:

set log Chat Command Phase             #turn on some logging. See man ppp.conf
enable pap                                          #turn on chap and pap accounting
enable chap
allow mode direct                      #turn on ppp bridging
enable proxy                           #turn on ppp proxyarping (redundant of a
disable ipv6cp                         #we don't use ipv6, don't want the errors
set mru 1492                           #set mru below 1500 (PPPoE MTU issue)
set mtu 1492                           #set mtu below 1500 (PPPoE MTU issue)
set ifaddr 10.0.0.1 10.0.1.1-10.0.5.254
set speed sync
set timeout 0
enable lqr
accept dns

4. edit /etc/ppp/ppp.secret username password

Reboot.

Hint: You could configure ipfw firewall to deny any to any and then make a script (easy) for every ppp connection to add a rule in firewall to allow ip for that connection.

Valuable Advices: - If you use different versions of windows boxes (not only xp) let enable pap and chap too - If you want a user to be connected only once (so users cannot give username and passowords to others to use the same account) you must setup a radius server (freeradius or radius-cistron, from ports collection). - If you have problems login in from windows box than set speed sync from /etc/ppp/ppp.conf might help you - pppoed daemon consumes some cpu so a faster cpu is better, also for many users is better to have more ram (512 or 1024 MB) - If you have problems stop your pppoed process (/etc/rc.d/pppoed stop) then launch pppoed with -Fd option instead -d, from command line to have pppoed in foreground to see errors. - On a lan with many users I had a problem, i guess some of the clients had a misconfigured pppoed server so it keeps asking for connection to pppoed server, flooding, forking the pppoed daemon continously. It is a patch that might solve this problem, I've read about it here: http://lists.freebsd.org/pipermail/freebsd-hackers/2005-February/010136.html , but could not find that patch.
