Remote access to local network via security gateway

摘要

Multiple protocol tunnels (e.g., IPsec tunnels) are deployed to enable an access terminal that is connected to a network to access a local network associated with a femto access point. A first protocol tunnel is established between a security gateway and the femto access point. A second protocol tunnel is then established in either of two ways. In some implementations the second protocol tunnel is established between the access terminal and the security gateway. In other implementations the second protocol tunnel is established between the access terminal and the femto access point, whereby a portion of the tunnel is routed through the first tunnel.

主权项

1. A method of communication, comprising:
establishing a first protocol tunnel between an access point on a local network and a security gateway; obtaining an address on the local network for an access terminal to enable the access terminal to remotely access the local network via the first protocol tunnel; establishing a second protocol tunnel between the access point and the access terminal via the first protocol tunnel such that at least a portion of the second protocol tunnel is established within the first protocol tunnel; sending a message including the address of the access terminal from the access point to the security gateway via the first protocol tunnel; receiving a packet from the local network at the access point; and transmitting the packet via the second protocol tunnel to the security gateway, wherein the security gateway forwards the packet to the access terminal.
