Matt Kassawara already proposed that solution but unfortunately it'll not
solve that issue. In previous messages is my explanation.
My idea is to implement quorum mechanism into Neutron and additionally
increase the stability of this solution thru implementing VRRP load
balancing feature. Multiple routers are active in same subnet but only for
a specific hosts. These will increase throughput of the network in SNAT
situation and additionally on routers failure only part of machines will
loose connectivity for around 5-8 seconds.
