The Teltonika is used as a 4G modem configured to pass through the public IP address to my security appliance it is connected to WAN PORT 1 of the security appliance I also have a satellite connection for backup connected to WAN PORT 2 of the security appliance.
The security appliance is configured to send a notification when the uplink changes. This is where the problem occurs, Since the DHCP lease time has been removed and defaulted to 1 hour I am now receiving a notification hourly that the uplink has failed as the connection is momently lost while the DHCP address is re-leased. Removing this notification is NOT an option as high availability for the site is required and when a link is down it must be investigated urgently.
Please can the option to increase lease time be re added or set to an infinite time?
