FreeBSD で xDSL を使う方法についてです.

私の経験では、

DION の ADSL/XDSL(PPPoE) で通信しよう

カーネルの再構築

次のように設定してカーネルを再構築します.
options NETGRAPH
options NETGRAPH_ETHER
options NETGRAPH_PPPOE
options NETGRAPH_SOCKET

/etc/ppp/ppp.conf の設定

設定に冗長なところがあるかも知れませんが、通信できたので、追求をやめま した。 なお、「 set device PPPoE:vr0」の行は、お使いのイーサネットデバイスに 合わせて変更してください。

default:
 set log Phase Chat LCP IPCP CCP tun command
 ident user-ppp VERSION (built COMPILATIONDATE)

 # Ensure that "device" references the correct serial port
 # for your modem. (cuaa0 = COM1, cuaa1 = COM2)
 #
 set device PPPoE:vr0
 set MRU 1454
 set MTU 1454
 add default HISADDR
 set server /var/run/internet "" 0177
 set dial
 set authname <ログインID>
 set authkey <ログインパスワード>

papchap:
 #
 # edit the next three lines and replace the items in caps with
 # the values which have been assigned by your ISP.
 #

 set authname <ログインID>
 set authkey <ログインパスワード>
 set openmode active
 accept pap

 set ifaddr 10.0.0.1/0 10.0.0.2/0 255.255.255.0 0.0.0.0
 add default HISADDR                    # Add a (sticky) default route

/etc/rc.conf

次の3行を追加です.
ppp_enable="YES"
ppp_mode="ddial"
ppp_profile="papchap"

通信できなかったら、

/var/log/ppp.log にログが残っているので、これでうまく行かない原因を推理します.

うまく通信できているときのログの例(一部分です)
