A system and method for determining whether to establish a connection between a first node and a second node in an ad-hoc network includes the step of sending from the first node to the second node a first message, where the first message includes a network identifier and a point of attachment identifier. The first message is received by the second node and the network identifier and the point of attachment identifier of the first message is compared with a network identifier and point of attachment identifier stored in the second node. The second node determines whether to establish the connection between the first node and the second node based upon the comparison. The point of attachment identifier is associated with a node of the ad-hoc network that provides communication with another network, which the node identifies, via an access point of the other network.
