Question

Hi,

I have an RUT240 on a mobile connection out in the field.  I have a port open pointed to a device, but I want to lock it down to a couple of external IPs.  I can add one IP in the Source IP address field, but can't see how to add multiple like the documentation suggests here https://wiki.teltonika.lt/view/Firewall#Port_Forward_Rule_Configuration

I've tried different configs of square brackets, colons, semi-colons, commas.....  Any help would be greatly appreciated.

Thanks

Kristian

Hi,

Regarding to your question on how to use the Firewall IP range. Could you try specifying instead of 192.168.10.1-192.168.10.5 use it's network mask 192.168.10.0/29 for 8 IP address but 6 usable host IP's from 192.168.10.1 until 192.168.10.6.

Hope it helps :)
