Apparatus and method for secure communication over restricted network

A client device comprising memory and a processor, wherein the processor is configured to execute instructions stored in the memory causing the processor to perform:

• forward data across a first communication network to a virtual private network (VPN) server, wherein the data is destined for a remote server;
• forward a request sent outside the VPN server to access a second communication network detected by the client device;
• receive a captive portal requiring authentication information;
• forward the authentication information to an authentication server to obtain access to the second communication network, wherein the authentication information is not forwarded to the VPN server;
• and
• forward and receive additional data to the VPN server concurrently across the first communication network and the second communication network.

A non-transitory computer readable storage medium configured to store instructions that when executed cause a processor to perform:

• forwarding, via a client device, data across a first communication network to a virtual private network (VPN) server, wherein the data is destined for a remote server;
• forwarding a request sent outside the VPN server, via the client device, to access a second communication network detected by the client device;
• receiving, via the client device, a captive portal requiring authentication information;
• forwarding, via the client device, the authentication information to an authentication server to obtain access to the second communication network, wherein the authentication information is not forwarded to the VPN server;
• and
• forwarding and receiving additional data, via the client device, to the VPN server concurrently across the first communication network and the second communication network.
