I have got a Lancom Router (1781va-4G) which was configured to work with Lancom Firewall. We changed the Lancom Firewall with an Cisco Meraki MX67 almost 3 months ago and the lancom router was not needed since last week. The 1781va-4G works with a sim card. How can I add this router to my network and join it to a specific subnet?
I do not have physical access to the device and have to solve this problem remotely. Every answer is appreciated and welcome. Thanks in Regards for the answers.
