Description of problem: Currently, SNAT traffic from the Compute Node to the NAPT Switch always goes through overlay tunnels by design, even when the tenant networking is VLAN. This is a design oversight on Netvirt. Ideally the SNAT traffic should go via the tenant network for reaching the NAPT Switch from where its sent to the external network. +---------------------------+ | 8.8.8.8 (External Server) | +-----------+---------------+ | +------+-------------+----------------------+ | External Network (FLAT/VLAN) | | ---+-------------------------------+-------+ | | Tenant VLAN Network | | | | | | | +-+------+---------+ +-----------+---------+ | ComputeNode | | ComputeNode | | hosting | | hosting | | NAPT Switch | | VM | +------------------+ +---------------------+
