IPフィルタ(pass)設定 (administratorで実行)


# ip filter 2000xx pass * 192.168.xxx.xxx tcp * www
# ip filter 2000xx pass * 192.168.xxx.xxx tcp * https
# pp select 1
pp1# ip pp secure filter in 2000xx 2000xx
pp1# pp select none
# save


静的IPマスカレード設定 (administratorで実行)


# nat descriptor masquerade static 1 1 192.168.xxx.xxx tcp www
# nat descriptor masquerade static 1 2 192.168.xxx.xxx tcp https
# save


Password: (そのままEnter)
> administrator
Password: (そのままEnter)
# ip lan1 address 192.168.xxx.xxx/24 (ルータのIPアドレス設定)
# save
# restart

これで、lan1にプライベートIPの設定が完了です。ルータの再起動が終わったら再度TELNETでログインします。
次は基本設定と、PPPoEの設定 (administratorで実行)

# nat descriptor log on
# nat descriptor masquerade ttl hold auto
# nat descriptor type 1 masquerade
# nat descriptor address outer 1 ipcp
# nat descriptor address inner 1 auto
# pp select 1
pp1# pp name "接続先の名称"
pp1# pp always-on on
pp1# pppoe use lan2 (WANは、lan2を使用する)
pp1# pppoe auto connect on
pp1# pppoe auto disconnect off
pp1# pp auth accept pap chap
pp1# pp auth myname (アカウントID) (パスワード)
pp1# ppp lcp mru on 1454
pp1# ppp ipcp ipaddress on
pp1# ppp ipcp msext on
pp1# ppp ccp type none
pp1# ip pp mtu 1454
pp1# ip pp intrusion detection in on reject=on
pp1# ip pp intrusion detection out on reject=on
pp1# ip pp nat descriptor 1
pp1# pp enable 1
pp1# pp select none
# ip route default gateway pp 1
# dns server pp 1
# dns private address spoof on
# dhcp service server
# dhcp scope 1 192.168.xxx.xxx-192.168.xxx.xxx/24
# save

これで、インターネットには接続できます。
次に、IPフィルタなどのセキュリティ設定をします。

# security class 2 off on
# timezone +09:00

# console lines infinity
# login timer 1800 (ログインタイマーは少し伸ばす)

# tftp host none

# httpd host lan1
# upnp use on
# upnp external address refer pp 1
# ip filter source-route on
# ip filter directed-broadcast on

レポートメール設定例

# mail-notify status use on
# mail-notify status server (メールサーバのIP)
# mail-notify status from (送信元メールアドレス)
# mail-notify status to 1 (送信先メールアドレス)
# mail-notify status subject "RTX1000 : Report"
# mail-notify status timeout 30
# mail-notify status type all
# save

IPマスカレードによる、ポート開放は次回にでも。

書き忘れてた分追記
パスワードは、必ず設定しておきましょう。

# login password
# administrator password

すべてのポートが、[緑]Stealthなら、OKです。
