Purpose
Use the Aloha as an IPv6 to IPv4 gateway without modifying anything on your current platform.
Target Network Diagram
Context
The website is available through IPv4 on the service IP 192.168.1.254. The IPv4 router does NAT IPv4 public address to this service IP.
About IPv6, the website hostname resolves directly on the IP 2001::2254, which is the IPv6 service IP hosting the service. The router just routes traffic to the Aloha.
All IPv6 traffic will be automatically translated to IPv4 by the Aloha: nothing to change on your servers and your servers don’t even need to be IPv6 compliant.
Configuration
Aloha 1 network configuration
On the GUI, click on Services > network > eth0 setup icon , then update the configuration as below:
service network eth0
vrrp id 254
vrrp garp 30
vrrp prio 100
vrrp no-address
vrrp address 2001::2254
vrrp address 192.168.1.254
vrrp address 2001::2254
ip6 address 2001::2201/96
ip address 192.168.1.201/24
mtu 1500
Click on [OK], then [Close].
Once the configuration has been updated, you need to reload the services:
- Network: Click on Services > eth0 reload icon
- VRRP: Click on Services > vrrp reload icon
Aloha 2 network configuration
On the GUI, click on Services > network > eth0 setup icon , then update the configuration as below:
service network eth0
vrrp id 254
vrrp garp 30
vrrp prio 99
vrrp no-address
vrrp address 2001::2254
vrrp address 192.168.1.254
vrrp address 2001::2254
ip6 address 2001::2202/96
ip address 192.168.1.202/24
mtu 1500
Click on [OK], then [Close].
Once the configuration has been updated, you need to reload the services:
- Network: Click on Services > eth0 reload icon
- VRRP: Click on Services > vrrp reload icon
Layer 7 (HAproxy) configuration
This configuration is common to both Aloha load balancer.
Add the bind on the IPv6 service address in the corresponding frontend section:
frontend ft_myappli
bind 192.168.1.254:80
bind 2001::2254:80
mode http
log global
option httplog
maxconn 1000
timeout client 25s
default_backend bk_myappli
Click on [OK], then [Apply].
