Methods and systems at a portable gateway of sending and receiving internet protocol (IP) data packets through a wireless gateway

A portable gateway for connecting to a wide area network (WAN) through at least one gateway, wherein the portable gateway is connected to at least one device through a local area network (LAN), comprising:

• at least one processor;
• at least one network interface;
• and
• at least one non-transitory computer-readable storage medium;
• wherein the at least one non-transitory computer-readable storage medium stores program instructions executable by the at least one processor for:
• (a) generating a web page;
• wherein the web page comprises input fields allowing to configure at least one WAN interface of the portable gateway;
• (b) storing the web page;
• (c) receiving a first Internet Protocol (IP) data packet from at least one device for forwarding;
• (d) when the first IP data packet is not capable of being forwarded through the at least one WAN interface after receiving the first IP data packet from the at least one device, sending the web page to and displaying the web page at the at least one device;
• (e) receiving information from the at least one device through the web page;
• (f) configuring, based on the information, the at least one WAN interface;
• and
• (g) establishing, by using the information, at least one connection to connect to the at least one gateway through the at least one WAN interface via at least one connection to forward the first IP data packet through the at least one WAN interface via the at least one gateway;
• wherein:
• the web page is configured to display available connections in the at least one device and the available connections are reachable to the portable gateway;
• and
• the at least one connection is selected from the available connections to be established at step (g) according to a predefined scheme.
