Tried portforwarding Technicolor modem and it won't save after I enable it. (See screenshot). Why?

0-60000 and correct IPv4 address for my modem and "Enable" and it did not save.

You can't use "0". You also should not forward large numbers of ports. Port forwarding is very risky to begin with, the NAT function is protecting your internal machines from traffic coming into your house from the internet. You want to limit it to just the ports that are really needed.

If you would need to port forward all the ports there likely is another setting someplace in the router that does that. Many routers call it DMZ even though it is not even close to the firewall concept of DMZ it is more a rule that forwards all ports to a internal IP.
