An embodiment directed to a method is associated with a VPN that may be used to access resource servers. Upon determining that the VPN has been accessed by a specified client, resource servers are identified, which each has an address and may receive traffic routed from the client through the VPN. The method further comprises sending a message corresponding to each identified resource server to the client, wherein the message to corresponding to a given one of the identified resources is intended to cause a response to be sent from the client to the address of the given identified resource server.
