22.2. IPv6 Multi WAN¶

IPv6 Multi WAN can be configured if VT AIR is connected to multiple ISPs which each provide an IPv6 address or IPv6 network address range.

22.2.1. Network Prefix Translation (NPTv6)¶

IPv6-to-IPv6 Network Prefix Translation (NPTv6) is a specification for IPv6 to achieve address-independence, similar to network address translation (NAT) in Internet Protocol version 4 (IPv4).

The setup for IPv6 Multi-WAN is very similiar to IPv4. The main difference is that you need to define a Network Range in SNAT to achieve NPT.

Create a second SNAT Rule for WAN2.

Additionally you need to add the WAN2 Gateway to the main routing table in Routing Tables for a Multi-Gateway Setup Multi-Gateway Setup.
