Abstract
Middleware forwards packets to a service prior to modification according to functionality of the middleware. Packets received from the service are identified as having been previously received. The packets are then modified by the middleware and forwarded to a destination. A hash of a packet and a TTL thereof may be stored by the middleware prior to forwarding the packet to the service. The TTL of the packet may be decremented before forwarding. A packet having a hash matching a stored hash and a TTL lower than the stored TTL may be deemed to have been previously received. Modification may include NAT, encryption, and/or description. The service may be a firewall, IDS, and/or IPS.
