Networking: Virtual Router Redundancy Protocol (VRRP)
I think it would be a good idea for Astaro to have VRRP capability. I know that it can be covered (at some point) with Uplink Balancing & Multipath Rules, or with Clustering/HA, but sometimes you have existing routers from other vendors that you don't want to throw them, and still provide some kind of failover capability to your network.
Also it helps during migration. It should be standard function.
