Abstract
A host with a firewall and an offload device can be configured/programmed to balance security and cost. Services are instantiated on the firewall and on the offload device. The service on the firewall maintains data for offloaded flows that indicate the next-hops for the offloaded flows when offloaded. The service on the offload device periodically copies samples from offloaded flows and communicates the samples to the service on the firewall. The service on the firewall determines a next-hop for the copied samples according to the firewall's routing information. If the determined next-hop has changed from what is indicated in the offloaded flows data, then the service on the firewall updates the offloaded flows data and communicates the next-hop change to the service on the offload device which causes an update to the flow table on the offload device for relevant offloaded flows.
