Examples relate to the configuration of network connections for computing devices. In some examples, a computing device determines that a network is inaccessible through a first network connection provided by a network access node. The computing device determines that the network is accessible through a first computing device that provides a second connection to the network. The computing device generates gateway configuration data for a second computing device based on an address for the first computing device. The computing device transmits the gateway configuration data to the second computing device to cause the second computing device to use the first computing device as a gateway.
