DigiWR31 - IP Passthrough WAN ->LAN0, no internet

We are setting up a Digi WR31 to use (with dual SIM) as a ISP on a WAN interface for a Fortigate. We setup IP Passthrough, and see the cellular carrier IP address on LAN0 (on our test laptop). However I cannot ping or browse the web. Do we need a default static route to something? If so, we’ll have 2 sim’s/2 carriers.


Dear customer,

thanks for your question and welcome to Digi Forum.

If still doesn’t help, please send us an email to tech.support@digi.com to create a case, providing the IMEI of the unit as well as a complete debug.txt file so we can check the configuration.
