A gateway in SONA is a special compute node, which plays role as a connection point to external networks. It performs NAT and PAT for outbound traffics and also exchanges routes to external routers with BGP or OSPF. Scalable gateway provides load balancing and high availability by allowing multiple redundant gateways to the system.
