Using IPv6


OPNsense fully supports IPv6 for routing and firewall. However there are lots of different options to utilize IPv6. Currently these scenarios are known to work:

  • Native IPv6 only

  • Dual Stack IPv4 + IPv6

  • IPv6 <-> IP4v Tunnel broker


NAT64, IPv4 <-> IPv6 Network address translations, is currently not supported by FreeBSD.
