Sierra Raven XE - Default gateway

How can i set “default gateway” on the Sierra Wireless Raven XE?

The Raven XE is connected to another network segment than the Ignition Gateway, so traffic needs to pass through our gateway.

You will need to bridge the two networks so you can connect the Raven XE, or, place the Raven XE on the same network segment the Ignition Gateway is on.
