5月に「NanoPi R2S+openWRT 21.02.0RCでBIGLOBEのMAP-E接続」にてOpenWRT 21.02.0-RC版での手順を作成した。
しかし、OpenWRT 21.02.0リリース版になってみると、いろいろ設定画面が変更となり、この手順のままでは動作させることができなかった。
ぐぐってみたところ「OpenWrt(21.02)でIPv6インターネットを使う」に手順があったので、参考にしつつ手順を更新した。
前書き
OpenWRTルータを作成するにあたり、いろいろある選択肢からRockchip RK3328のNanoPi R2S と Rockchip RK3399のNanoPi R4S を候補にあげた。
Amazon日本の倉庫に在庫があるというのと、openWRTのページに「FriendlyARM NanoPi R2S」とデバイスに関する個別ページが作成されており、リリース版の提供がされていたので、NanoPi R2Sを買って設定を行った。
ちなみに置き換え対象となったGL-MV1000とのサイズ比較はこんな感じ
OpenWRT 21.02.0-RC版の時代はアップグレードしたら以前の設定を残しておくと起動しなくなるとか問題もありましたが、OpenWRT 21.02.0リリース版を書き込んだあと設定復旧で動作させることができました。
設定手順0: MicroSD作成
friendlyarm_nanopi-r2s-squashfs-sysupgrade.img.gz を展開したものをmicroSDに書き込んでNanoPi R2Sを起動。
設定手順1:パッケージの追加
mapパッケージと日本語UIパッケージ(luci-i18n-base-ja)をインストール
また、後述のニチバン対策を行う場合は iptables-mod-ipopt もインストールする。
GUIの場合、[システム]-[Software]にて、「Update lists」を実行してパッケージ一覧を取得した後に、「Filter」にパッケージ名を入れて、出てきたモジュールを「Install」する。
CLIでインストールする場合は以下を実行
# opkg update
# opkg install luci-i18n-base-ja
# opkg install map
# okpg install iptables-mod-ipopt
インストール後は再起動を行うこと。
再起動しないとluciのネットワーク設定で「プロトコル:MAP / LW4over6」が選択肢に現れません。
設定手順2:WAN6インタフェースの作成
WAN6インタフェースがなければ「プロトコル: DHCPv6クライアント」で作成する
最初はそのまま設定して、有効化し、WAN6インタフェースに割り当てられるIPv6アドレスを確認すること。
↑の画像は使い回しなので、この段階では無いはずの「MAP」インタフェースなどが入ってます
上記のようにWAN6インタフェースに「IPv6」アドレスが確認できたら、そのアドレスをコピーして、notepadにでも貼り付けておきます。
設定手順3:WAN6インタフェースにDHCPv6関連設定
openWRT 21.02.0のリリース版になったらWAN6インタフェースではDHCPv6関連設定がGUIできるようになりました。
[DHCPサーバー]を選択して、下記のようになっている場合は「DHCPサーバーをセットアップ」をクリックします。
クリックしたあと[一般設定]タブは下記のような感じで変更せず
[IPv6設定]タブで下記の設定を行います。
Designated master: チェックを入れる
RA-Service:リレーモード
DHCPv6-サービス: リレーモード
NDP-Proxy: リレーモード
(Learn routesは設定を変更していない)
設定手順4:LANインタフェースにDHCPv6関連設定
LANインタフェースの[DHCPサーバー]-[IPv6設定]で以下の設定を行います。
RA-Service:リレーモード
DHCPv6-サービス: サーバーモード
NDP-Proxy: リレーモード
(マスターにチェックは入れません)
設定手順5: IPv6 PD設定
OpenWRT 21.02.0-RC版だとIPv6 PD設定がWAN6にあったのですが、リリース版だと消えています。
これは別のインタフェースとして作成することで対応するようです。
[インタフェースを新規作成]から下記でインタフェースを作成します。
名前:WAN6PD
プロトコル:静的アドレス
デバイス: WAN6インタフェース(@wan6表記)
詳細設定では手順2で確認したIPv6アドレスを使います。
IPv6アドレスが「IPv6: wwww:xxxx:yyyy:zzzz:aaaa:bbbb:cccc:dddd/64」というようになっているとき、先頭の4カラム「wwww:xxxx:yyyy:zzzz」を使います。
まず、WAN6PDに割り当てる 「wwww:xxxx:yyyy:zzzz::1001」を「IPv6アドレス」に設定します。
「IPv6 ゲートウェイ」には「wwww:xxxx:yyyy:zzzz::1 」を指定します。このアドレスは設定完了後、WAN6PDインタフェースではなく、LANインタフェースに対して割り当てられます。
「IPv6ルートプレフィックス」には「wwww:xxxx:yyyy:zzzz::/56」と指定します。
設定すると上記のような感じです。
設定手順6: MAP-E接続設定
インタフェースの新規作成で「プロトコル:MAP / LW4over6」を作成して、必要な値を入れていきます。今回は「WAN_MAP」で作成しました。
[一般設定]では下記の様にしました。
プロトコル:MAP/LW4over6
タイプ:MAP-E
以後は環境に合わせた値
[詳細設定]では「従来のMAPを使用」にチェックを入れる
設定手順7: 各インタフェースのファイアウォールゾーン設定
wan系のゾーンに「wan_map」と「WAN6PD」を追加します。
設定完了
ひとまずこれで設定完了です。
うまく接続が始まらない場合は、再起動してみてください。
設定:ニチバン対策
通称「ニチバンベンチ」と呼ばれているものがある。
一部のIPv4通信のみが可能なサイトにアクセスした際に、一定数以上の通信が行えなくなりコンテンツが欠けるなどの現象が発生することがある。
これはNATテーブルの利用手法と、一回確保したNATテーブルエントリの有効期限設定の兼ね合いで、MAP-Eで確保できるIPv4通信用のNAT用ポートを使い果たしてしまった場合に発生している。
大量の小さなファイルがWebサーバ側の同時セッション数が非常に多い設定で流れてこなければならないので、この現象が発生しているかどうかを意図的に確認するのがなかなか難しいものがある。
しかし、長らくニチバンサイトではその条件に合致するサイト構造であったため、ニチバンサイトを10窓ぐらいでリロードすれば発生していたため、確認手法としてニチバンにアクセスすることを「ニチバンベンチ」と呼称していた。(なお、2021年9月時点のニチバンサイトはサイト内容が一新され発生しなくなっている)
このNATテーブルとIPv4 ポート割り当ての問題を解消するためにiptablesを利用して割り当て手法の調整を行う https://paste.teknik.io/VeN9r を使用した。
IP4,PSID, TUNDEVは自分の環境に合わせて変更すること
IP4, PSIDがわからない場合は http://ipv4.web.fc2.com/map-e.html で確認すること
TUNDEVは、GUIから設定した名前ではなく、アイコンの下に小さく書かれている方の名前を使う。↑の場合は「map-wan_map」になる。
また、units1とunits2は、BIGLOBEはV6plus相当であるため、数値を変更する。
units1=15 #V6plus:15 OCN:63
units2=4096 #V6plus 4096 OCN:1024
IP4='xxx.xxx.xxx.xxx'
PSID='x'
TUNDEV='map-wan_map'
iptables -t nat -F PREROUTING
iptables -t nat -F OUTPUT
iptables -t nat -F POSTROUTING
rule=1
while [ $rule -le $units1 ] ; do
mark=`expr $rule + 16`
pn=`expr $rule - 1`
portl=`expr $rule \* $units2 + $PSID \* 16`
portr=`expr $portl + 15`
iptables -t nat -A PREROUTING -m statistic --mode nth --every $units1 --packet $pn -j MARK --set-mark $mark
iptables -t nat -A OUTPUT -m statistic --mode nth --every $units1 --packet $pn -j MARK --set-mark $mark
iptables -t nat -A POSTROUTING -p icmp -o $TUNDEV -m mark --mark $mark -j SNAT --to $IP4:$portl-$portr
iptables -t nat -A POSTROUTING -p tcp -o $TUNDEV -m mark --mark $mark -j SNAT --to $IP4:$portl-$portr
iptables -t nat -A POSTROUTING -p udp -o $TUNDEV -m mark --mark $mark -j SNAT --to $IP4:$portl-$portr
rule=`expr $rule + 1`
done
上記をopenwrtの[ネットワーク]-[ファイヤーウォール]-[Custom Rules] (/etc/firewall.user) に記載する。
また、[システム]-[スタートアップ]-[ローカルスタートアップ] (/etc/rc.local)の exit 0よりも前に下記2行を追加する
sleep 30
sh /etc/firewall.user
なお、iptablesのstatisticモジュールはiptables-mod-ipoptに入っているが、標準では導入されていないため、冒頭でインストールしているが、まだの場合は下記のような感じでインストールする。
root@nanopi:~# opkg install iptables-mod-ipopt

これはどうやら、openwrt起動後にSoftwareパッケージの個別更新を実施していたのだが、ネットワークのrestartが行われた際に、iptablesが再設定されたためだったようで、openwrt全体を再起動した正常になった。
現在行っている設定はネットワーク開始後に /etc/rc.local からiptablesの設定を追加しているので、rc.localで行うことが消えた、という感じである
