[SOLVED] Multi-WAN

[MenschAergereDichNicht]

I am back to BIOS version 4.14.0.6 for now.

I found the solution to the remaining problems.

Currently i have two APU4D4 connected to a Fritzbox that is my uplink to the fiber provider.
One is the production system with version 21.7 and the other runs the RC1.

The Fritzbox is configured to use 1GB/s on two ports and 100Mb/s on the other two.

One GB-Port of the Fritzbox is the upstream port to the fiber media converter. The other is connected to the production APU.
The RC1 was connected to one of the 100MB/s ports.

This configuration produced the described problems. The moment i disconnected the production system from the fritzbox and put the line of the RC1 box into the 1GB port evrything suddenly works.

I have currently no idea of the underlying reason. The production system has a different IPv4 address space and should not cause any problems.

Both systems are configured to use DHCPv6 and to request only an IPv6 prefix. Is it possible that this can cause address collisions? I could get a 56-er prefix but set "Prefix delegation size" to 60. My assumption was that i should be given a different prefix for each system.

The final solution was to adjust the third port of the Fritzbox to 1Gbit/s. It is a little bit strange that 100Mbits/s are not working (either Fritzbox or APU problem) but i can live with that.

Thanks for following up on these. Like with software a number of changes at once make it difficult to see what changed what.

BIOS issue is certainly not nice but good it can be fixed with a downgrade.
