| Setting up IPv6 | docs |

|
IPv6 may work out of the box in many cases. But in some cases or some specific provider, you may need to tweak things manually to enable IPv6.
With a VPS from OVH
OVH give one IPv4 address and one IPv6 address for VPS but by default, only IPv4 is OK. The OVH's documentation is here : https://docs.ovh.com/gb/en/vps/configuring-ipv6/
Configure the DNS server
Here : https://yunohost.org/#/dns_subdomains
Configure the server
On the OVH panel, you will copy 3 element :
- the IPv6 address
- the IPv6 gateway address
- the IPv6 prefix. On OVH's VPS SSD, prefixes are
/128because you have only one IPv6 address.
On your VPS, create a backup of the network configuration with : cp /etc/network/interfaces ~/interfaces in home directory.
Then, you can edit the configuration file (/etc/network/interfaces) with the following. It is assumed that :
! In this example, it is assumed that your network interface is eth0. If it's different (check with ip a) you need to adapt the example below.
iface eth0 inet6 static
address <your IPv6 address>
netmask <your IPv6 prefix>
post-up /sbin/ip -6 route add <the IPv6 gateway> dev eth0
post-up /sbin/ip -6 route add default via <the IPv6 gateway> dev eth0
pre-down /sbin/ip -6 route del default via <the IPv6 gateway> dev eth0
pre-down /sbin/ip -6 route del <the IPv6 gateway> dev eth0
Now, save the file and restart the network service with : service networking restart. (TODO : ideally we should find a way to validate the content of the configuration, otherwise it could fuck up the network stack and get disconnected from the VPS ?)
Check your configuration with these commands :
ip ato display network interfaces and addresseshostname -Ito display the system IP addresses- try to ping an IPv6 server (for example you can use
ping6 ip6.yunohost.org) - try to ping your server from your PC (assuming your PC has IPv6 enabled)
If it's ok, it's ok !
