[Openvpn-devel] [PATCH] Adds support for setting the default IPv6 gateway for routes using the route-ipv6-gateway option

[James B. <ja...@sp...>]

This patch adds support for setting the default IPv6 gateway for routes using the "route-ipv6-gateway” option.

Currently if users try to use the "redirect-gateway ipv6” option, or a IPv6 route without a gateway, without using "ifconfig-ipv6" they’ll receive the message "OpenVPN ROUTE6: OpenVPN needs a gateway parameter for a --route-ipv6 option and no default was specified by either --route-ipv6-gateway or --ifconfig-ipv6 options”.

However, the "route-ipv6-gateway” option doesn’t actually exist, and it is required for bridged/TAP setups relying on IPv6 auto-configuration for IP assignment. This patch adds the "route-ipv6-gateway” option. The gateway specified must be an IPv6 address, FQDNs are not supported (to match the behaviour of the other IPv6 related options).

Currently in production use in Viscosity for macOS and Windows, no reported issues.
