IPv6

If you need IPv6, please make sure you can access internet using ipv6 before proceeding.

There are 2 types of connection:

NAT

• Internal IPv6 communication uses ULA (Unique Local Address).
• Prioritize on using public IPv6 (shared with all clients) and fallback to IPv4 when not available.

Full Routing

• Assign unique public IPv6 to each clients.
• You need to have an IPv6 address and a block of /64 IPv6 addresses.
  • IPv6 address should be assigned to main interface and /64 is reserved for wireguard
  • If you only get /64 from VPS provider, you need to split it into smaller blocks and install ndppd (see example)
  • If you don't have it, you can get free IPv6 from Tunnelbroker (see example)
