OpenWRT Configuration

This configuration makes a WAN interface from a gretun tunnel. The WAN IP is configured in DHCP.

In this configuration, the WAN is the private network of a 4G LTE modem/router that is plugged into a raspberry pi on the house wall. The raspberry py provides the modem/router network on a gretun tunnel.

• uptun0: gretap tunnel to raspberry py, attaches to upbridge0
• upbridge0: dhcp client to uplink (the gretap tunnel
