Hello,
I intend to add a 4G modem as a Standby Interface and want to limit the devices that can use the backup 4G to a select few. I understand that I can create firewall rules permitting connections via the primary Internet connection interface but the follow statement confuses me,
"After activation Firewall and DynDNS configuration options regarding the first interface are replaced by the newly created objects Uplink Interfaces and Uplink Primary Addresses."
It sounds like all of the firewall rules I've written to permit connections via the primary Internet interface, will automatically be rewritten and permit connections via the Standby Interface - which is what I need to avoid.
Am I understanding correctly? Any ideas as to how to limit the devices that can use the backup 4G Standby Interface?
Thx
