Systems and methods are provided to add flow validation information to packets of network traffic. Each packet can have flow validation information added corresponding to the source and destination of the packet. A stateful network routing service may intercept packets and obtain or generate flow validation information based on the source and destination of the packet. The stateful network routing service may add the information to the packet and transmit the enriched packet to a network appliance. The stateful network routing service may receive a second enriched packet from the network appliance. The stateful network routing service can compare the enriched packet with the second enriched packet. Based on the comparison of the enriched packets, the stateful network routing service can determine whether the packet should be transmitted to the destination or dropped.

Validating network flows in a multi-tenanted network appliance routing service

Techniques are described that enable users to configure the mirroring of network traffic sent to or received by computing resources associated with a virtual network of computing resources at a service provider network. The mirrored network traffic can be used for many different purposes including, for example, network traffic content inspection, forensic and threat analysis, network troubleshooting, data loss prevention, and the like. Users can configure such network traffic mirroring without the need to manually install and manage network capture agents or other such processes on each computing resource for which network traffic mirroring is desired. Users can cause mirrored network traffic to be stored at a storage service in the form of packet capture (or 'pcap') files, which can be used by any number of available out-of-band security and monitoring appliances including other user-specific monitoring tools and/or other services of the service provider network.

Mirroring network traffic of virtual networks at a service provider network

Disclosed are various embodiments of a stateful network router. In one embodiment, a network data connection is intercepted between a first host and a second host on a network. First data packets from the network data connection sent by the first host to the second host are routed to a target network appliance. Second data packets from the network data connection sent by the second host to the first host are also to the target network appliance.

Stateful network router for managing network appliances

Disclosed are various embodiments of a stateful network router. In one embodiment, a stateful network router intercepts a network data connection between a first host and a second host on a network. The stateful network router routes first data packets from the network data connection sent by the first host to the second host to a target. The stateful network router also routes second data packets from the network data connection sent by the second host to the first host to the target.
