the sagecom is going to use DHCP to assign IP addresses to whatever connects to it. I'm assuming it uses the range 192.168.x.0/24 but I don't know what x is so 192.168.0.0/16 should work regardless.
I checked the other settings, yes there is DHCP showing the sagecom internal ipadres. Default internal ip adres of sagecom is 192.168.1.1.
In firewall settings (column source ip address) I see 192.168.1.0 /24.
So If i change this source ip adres to the ip adres of my tp link external ipadres: 192.168.x.y without the /24 , will this limit the port only be accessible by tp link shared DHCP ip adresses?
So no other device will be able connecting to the sagecom modem/router as the ports will be not accessible by other ip adresses that thesegecom shares using DHCP?
Maybe aslo a good idea to limit the numbers of ipadress the sagecom can have ( pool start and pool end)?
