ネットワーク環境は、WAN側光電話なし、東NTT光をeth0に接続してます。LAN1は、公開サーバ用のネットワーク192.168.10.0/24です。こちらはPPoEのパケットを流し込みします。LAN2は、ネットサーフィン用のネットワーク192.168.1.0/24です。こちらにDS-Lite接続のパケットを流し込みます。

modify LAN_PBRがDS-LiteとPPPoEを両方を切り分けのポイントです。あと、PPPoE_LOCALのrule20,30はGoogle Cloud Platformとvpn接続のためのものです。VPN IPsec利用しないときは不要です。2.Interfacesの設定
interfaces {
ethernet eth0 {
description WAN(IPoE+DS-Lite+PPPoE)
duplex auto
firewall {
in {
ipv6-name WANv6_IN
}
local {
ipv6-name WANv6_LOCAL
}
}
ipv6 {
address {
autoconf
}
disable-forwarding
dup-addr-detect-transmits 1
}
pppoe 0 {
default-route auto
firewall {
in {
name PPPoE_IN
}
local {
name PPPoE_LOCAL
}
}
mtu 1454
name-server auto
password xxxx
user-id xxx@xxxxxx
}
speed auto
}
ethernet eth1 {
address 192.168.10.1/24
description LAN1
duplex auto
firewall {
in {
modify LAN_PBR
}
}
speed auto
}
ethernet eth2 {
description LAN2
duplex auto
speed auto
}
ethernet eth3 {
description LAN2
duplex auto
speed auto
}
ethernet eth4 {
description LAN2
duplex auto
speed auto
}
ipv6-tunnel v6tun0 {
description DSLite
encapsulation ipip6
firewall {
in {
name DSLite_IN
}
local {
name DSLite_LOCAL
}
}
local-ip 2409:xx:xx:xx:xx:xx:xx:xx
multicast disable
remote-ip 2404:8e00::feed:100
ttl 64
}
loopback lo {
}
switch switch0 {
address 192.168.1.1/24
description LAN2
firewall {
in {
modify LAN_PBR
}
}
mtu 1500
switch-port {
interface eth2 {
}
interface eth3 {
}
interface eth4 {
}
vlan-aware disable
}
}
}
pppoeとipv6-tunnelの設定はそれぞれの環境に合わせてください。eth1とswitchにfirewallで設定したmodify LAN_PBRを設定します。
3.Port-forwardの設定
port-forward {
auto-firewall enable
hairpin-nat enable
lan-interface eth1
rule 1 {
description http
forward-to {
address 192.168.10.202
port 80
}
original-port 80
protocol tcp
}
rule 2 {
description https
forward-to {
address 192.168.10.202
port 443
}
original-port 443
protocol tcp
}
wan-interface pppoe0
}
WANからのhttpとhttpsは、公開サーバに転送。4.Protocolsの設定
protocols {
static {
interface-route 0.0.0.0/0 {
next-hop-interface pppoe0 {
distance 200
}
next-hop-interface v6tun0 {
}
}
table 1 {
interface-route 0.0.0.0/0 {
next-hop-interface pppoe0 {
}
}
}
table 2 {
interface-route 0.0.0.0/0 {
next-hop-interface v6tun0 {
}
}
}
}
}
table1,2を追加して行き先をpppoe0かv6tun0を設定しています。
5.Serviceの設定
service {
dhcp-server {
disabled false
hostfile-update disable
shared-network-name LAN1 {
authoritative enable
subnet 192.168.10.0/24 {
default-router 192.168.10.1
dns-server 192.168.10.1
lease 86400
start 192.168.10.38 {
stop 192.168.10.199
}
static-mapping 10 {
ip-address 192.168.10.201
mac-address xx:xx:xx:xx:xx:xx
}
static-mapping 11 {
ip-address 192.168.10.202
mac-address xx:xx:xx:xx:xx:xx
}
}
}
shared-network-name LAN2 {
authoritative enable
subnet 192.168.1.0/24 {
default-router 192.168.1.1
dns-server 192.168.1.1
lease 86400
start 192.168.1.38 {
stop 192.168.1.199
}
static-mapping 20 {
ip-address 192.168.1.201
mac-address xx:xx:xx:xx:xx:xx
}
static-mapping 21 {
ip-address 192.168.1.202
mac-address xx:xx:xx:xx:xx:xx
}
static-mapping 22 {
ip-address 192.168.1.203
mac-address xx:xx:xx:xx:xx:xx
}
}
}
use-dnsmasq disable
}
dns {
dynamic {
interface pppoe0 {
service custom-duckdns {
host-name xxxx.duckdns.org
login nouser
password xxxx-xxxx-xxxx-xxxx-xxxx
protocol dyndns2
server www.duckdns.org
}
}
}
forwarding {
cache-size 150
listen-on eth1
listen-on switch0
system
}
}
gui {
http-port 80
https-port 443
older-ciphers enable
}
nat {
rule 5010 {
description "masquerade for PPPoE"
outbound-interface pppoe0
type masquerade
}
}
ssh {
port 22
protocol-version v2
}
}
dnsは、duckdnsの例です。PPPoEのIPを利用しています。6.Systemの設定
port-forward {
system {
host-name xxxx
login {
user xxxxxx {
authentication {
encrypted-password xxxxxxxxxxxxxxxxxxxxxxx
}
level admin
}
}
name-server 2001:4860:4860::8888
name-server 2001:4860:4860::8844
ntp {

}
offload {

}
static-host-mapping {
host-name xxx {

}
}
syslog {

}
facility protocols {

}
}
}
time-zone Asia/Tokyo

}
}
特に説明はいらないでしょう。それぞれの環境に合わせて設定してください。次回は、IPv6+DS-LiteとPPPoEが正しく動いているか確認したいと思います。
