Hello,

I'm trying to set up an ipsec server on a linux machine. The connection between clients and server should be IPv6 only but also needs to transport IPv4 packets.

However, the linux kernel doesn't seem to support a feature which is required to transport IPv4 packets within an IPv6 ipsec connection, as shown here:

Does maybe one of you know how to transport IPv4 packets in an IPv6 ipsec connection, or do we need to wait for the linux kernel to support this feature? Because this stops me from switching to IPv6 ipsec connections and I would like to reduce the usage of IPv4 as much as possible ...

Sorry if this might be off-topic from the general IPv6 WG topics, but I thank you in advance for your time and answers!

Best regards,

Michael Hock
