Abstract: A method includes obtaining, at a first electronic device, first and second proxy auto-configuration (PAC) files. The method also includes executing, by the first electronic device, a first local proxy server configured to receive traffic forwarded by the first electronic device and at least one second electronic device. The first local proxy server is configured to forward the traffic based on the first PAC file. The method further includes executing, by the first electronic device, a second local proxy server configured to forward the traffic from the second electronic device(s) to the first local proxy server based on a second PAC file. The method also includes receiving, at the first local proxy server from the second local proxy server, the traffic from the second electronic device(s). In addition, the method includes forwarding, using the first local proxy server, the traffic from the second electronic device(s) to an external proxy server.

Abstract: A method includes enabling, by a tethering device that is tethered to a tethered device, a firewall to redirect network traffic from the tethered device to an authentication application executing on the tethering device. The method also includes receiving, by the tethering device from the tethered device, a user certificate of the tethered device during an authentication process. The method further includes verifying, by the tethering device, the user certificate of the tethered device using a certificate authority (CA) certificate of the tethered device that is installed on the tethering device. In addition, the method includes, in response to successful verification of the user certificate of the tethered device, disabling the firewall to allow the network traffic to and from the tethered device.
