Classification: CPC H  G | IPC H

Claim 0:
1. A method comprising:
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;
evaluating an access control list (ACL) for the packet with a source virtual network interface card (source VNIC);
embedding ACL information relevant to the packet in the packet;
forwarding the packet to a virtual switching and routing service (VSRS), the VSRS coupling a first virtual layer 2 network (VLAN) with a second network;
identifying with the VSRS 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;
accessing with the VSRS the ACL information from the packet; and
applying the accessed ACL information to the packet.
