Before you do that, if you're using an IPv6 VPN IP, and your LAN interface has no IP6 network assigned to it, then add one by going to Interfaces -> LAN and change IPv6 configuration to "Static IPv6", then pick an address pool under "Static IPv6 Configuration" (I.e., fd00:20:20::/64) Go to Firewall -> NAT -> Outbound. Select "Manual Outband NAT rule generation", then click the Save button, then Accept Changes.
