I have the problem, that I must access the control webui of an bridge, which understand only IPv4 from an IPv6 only station.
From the router itself it will works, because I have set an IPv4 address of the bridge management network to the port where the bridge is connected.
So my idea is, to use 4in6 to connect to the router which than do nat to forward it to the IPS bridge.
But I never has done this before using Mikrotik.
Here an logical picture of the setup:
At the same time, I sent a request to support asking whether NAT64 could be implemented. Since RouterOS is based on Linux, it should be possible to add one of the two known implementations.
