Claim 17:
18. A system comprising:
a physical network comprising:
at least one first processor, the at least one processor is configured to:
send a packet from source compute instance in a virtual network instantiated on the physical network to a destination compute instance via a destination virtual network interface card (destination VNIC) within a first virtual layer 2 network instantiated on the physical network;

a network virtualization device, the network virtualization device configured to:
instantiate a source VNIC, the source VNIC configured to:
evaluate an access control list (ACL) for the packet;
embed ACL information relevant to the packet in the packet; and
forward the packet to a virtual switching and routing service (VSRS), the VSRS coupling a first virtual layer 2 network (VLAN) with a second network;

at least one second processor, the at least one second processor configured to instantiate the VSRS, the VSRS configured to:
identify the destination VNIC for delivery of the packet based on information received with the packet and mapping information contained within a mapping table;
access the ACL information from the packet; and
apply the accessed ACL information to the packet.
