Dual-protocol network

[ajoeiam]

Greetings

Did a search and find no information.
Have been digging into networking over the last weeks.
Was pointed to a document where they are talking about a dual-protocol network ie a network where ipv4 is used for outside communication and ipv6 for lan (inside communication).

Is there a way to setup OPNsense to do this dual-protocol networking?

TIA

You will need a gateway for each application protocol you want to support. In the most basic case, you would run a Squid proxy on OPNsense which accepts IPv6 clients and makes IPv4 web and file transfer connections on their behalf. https://docs.opnsense.org/manual/proxy.html

DNS, SMTP and NTP are supported as well and you can run a socks proxy to cater for more esoteric cases.
