IX2005でPPPoE+IPoE接続

高速VPNアクセスルータ NEC Univerge IX2005 が手に入ったので、低速なCisco1721から乗り換えてみた(^^♪ 高速というだけあって、v4もv6もほぼ100Mbps出るぅ～。(Cisco1721は最大8Mbpsぐらいしか出ない・・・) 人気のIX2015と違って、IX2005はPPP、VPN、BAKランプが付いてる。特にPPPランプが付いてるのは便利♪ そのかわりFastEthernetが一つ少なくて、BRIポートも無い(今時BRIイラネ・・・)。筐体の大きさはIX2015の半分くらい。コンパクトでGood！

IPv6パススルー (IPoE)

access-list ipv6path permit src any dest any type ipv6

access-list ipv6path permit src any dest any type ip

bridge irb enable　//Integrated Routing and Bridging

no bridge 1 bridge ip　//IPv4はWAN側へブリッジングせずにルーティング+NAPTする

//FE0とFE1をブリッジグループ1に追加

interface FastEthernet0.0

　description WAN

　filter ipv6path 1 in

　bridge-group 1

　no shutdown

interface FastEthernet1.0

　description LocalLAN

　filter ipv6path 1 in

　no ipv6 nd import-prefix

デフォルトルートをPPPoEに

ip route default FastEthernet0.1

LAN向けDHCP

ip dhcp enable

ip dhcp profile lan

　assignable-range 192.168.24.2 192.168.24.50

　default-gateway 192.168.24.1

　domain-name yuriko.local　//無くてもいいｗ

interface FastEthernet1.0

　ip dhcp binding lan

Telnet、httpアクセス

username admin password hash ********** administrator　//Telnetユーザ名とパスワード

telnet-server ip enable

telnet-server ip access-list telnet

ip access-list telnet permit ip src 157.7.234.135/32 dest any　//所有ConoHa VPSからのアクセス許可

ip access-list telnet permit ip src 192.168.24.0/24 dest any　//LAN内からのアクセス許可

http-server username admin

http-server ip access-list telnet

http-server ip enable

Telnetアクセス(IPv6)

ipv6 access-list telnet6 permit ip src 2001:470:24:a17::0/64 dest any

ipv6 access-list telnet6 permit ip src 240b:252:8a0:100::0/64 dest any

ipv6 access-list telnet6 permit ip src fe80::0/10 dest any

telnet-server ipv6 enable

telnet-server ipv6 access-list telnet6

？？？

ip ufs-cache enable

デフォルトルートをIPoEに　(JPNE系v6網の場合「PREFIX::fffe」にするとインターネットへルーティングされる模様)　ルータにv6グローバルアドレスを振らない場合は設定しなくてもいい。

ipv6 route default 240b:252:8a0:100::fffe

DNSサーバ(IX2005をLAN内向けDNSとして稼働させる)

ip name-server 8.8.8.8　//Google Public DNS

ip name-server 8.8.4.4　//プロバイダのDNSでもいい

dns cache enable
