概要

FITELnet F200とNCXX UX302NCでpovo2.0に繋ぐ設定例を紹介する。

構成と設定

想定構成

USB 1: NCXX UX302NC

最小限の設定例

conf t
interface dialer 1
 ip nat inside source list 1 interface
 caller *99***1#
 ppp account user@povo.jp povo
exit
interface modem 1
 idle-timer send off
 idle-timer receive off
 forced disconnect packet off
 forced disconnect cumulative-time off
 auto connect on continuous
 modem out-strings init 1 at+cgdcont=1,"IP","povo.jp"

うまくいかないとき

NDISモードになっている

NDISモードのときは以下のように認識される。この状態のときは動かないため、Windows PCのConnection ManagerでRASモード(modem)に設定して保存する。その他うまくいかないときもConnection Managerで状態を確認して再設定する。
