Hello, Ok, thanks Wido. I have now sorted out the correct network configuration and deployed new mon's with the new IP. Everything is now on the new IP and works so far.

They need to bind to a specific IP and that can't be 0.0.0.0 You then need to make sure proper routing is in place so all clients and OSDs can talk to the MONs. So don't attempt anything like NAT. Make sure everything works with proper IP-routing.
