SYSTEM AND METHOD FOR ROUTING SELECTED NETWORK TRAFFIC TO A REMOTE NETWORK SECURITY DEVICE IN A NETWORK ENVIRONMENT

摘要

A method provided in one example includes receiving a request for configuration information for a host in a first network, determining whether the request was sent over a quarantine virtual local area network (VLAN) in the first network, and providing to the host a network address of a first domain name system (DNS) server if the request was sent over the quarantine VLAN in the first network. In addition, the first DNS server translates a domain name in a query from the host to a network address of a network security device in a second network. In more specific embodiments, the domain name in the query is mapped to a different network address in a second DNS server. The method may also include providing a network address of the second DNS server if the request was sent over a production virtual local area network (VLAN) in the first network.
