Systems and methods of interface-based ACLs in a virtual Layer-2 network. The method can include sending a packet from source compute instance in a virtual network to a destination compute instance via a destination virtual network interface card (destination VNIC) within a first virtual layer 2 network and evaluating an access control list (ACL) for the packet with a source virtual network interface card (source VNIC). ACL information relevant to the packet can be embedded in the packet. The VSRS can receive the packet and can identify the destination VNIC within the first virtual layer 2 network for delivery of the packet based on information received with the packet and mapping information contained within a mapping table. The VSRS can access ACL information from the packet and can apply the ACL information to the packet.

Interface-based ACLS in a layer-2 network

Systems and methods for a VLAN switching and routing service (VSRS) are disclosed herein. A method can include generating a table for an instance of a VSRS, which VSRS couples a first virtual layer 2 network (VLAN) with a second network. The table can contain information identifying IP addresses, MAC addresses, and virtual interface identifiers for instances within the virtual layer 2 network. The method can include receiving with the VSRS a packet from a first instance designated for delivery to a second instance within the virtual layer 2 network, identifying with the VSRS the second instance within the virtual layer 2 network for delivery of the packet based on information received with the packet and information contained within the table, and delivering the packet to the identified second instance.

Systems and methods for a virtual network routing gateway that supports address translation for data plane as well as dynamic routing protocols are disclosed herein. The method can include coupling a gateway with a plurality of ports to a network having a plurality of first IP addresses in a private address space, generating a Network Address Translation ('NAT') function in the gateway, inputting translation information into the NAT function, advertising routes based on the translation information, populating a unified routing table in the gateway based on the plurality of first IP addresses in the private address space and on translated route advertisements, receive an inbound network packet at the gateway, translating an inbound address of the inbound network packet with the NAT function, and delivering the network packet according to the routing table and based on the translated inbound address.

Virtual network routing gateway that supports address translation for dataplans as well as dynamic routing protocols (control plane)

Techniques are described for communications in an L2 virtual network. In an example, the L2 virtual network includes a plurality of L2 compute instances hosted on a set of host machines and a plurality of L2 virtual network interfaces and L2 virtual switches hosted on a set of network virtualization devices. An L2 virtual network interface emulates an L2 port of the L2 virtual network. Access control list (ACL) information applicable to the L2 port is sent to a network virtualization device that hosts the L2 virtual network interface.
