local network: how to change broadcast address (with GUI)

Question

Is there a way, to change the broadcast address for network config via GUI?

if I set my network config to "auto", connection establishes with following information for IPv4:

• IP-Address: 192.168.0.5
• Broadcast-Address: 192.168.1.255
• Subnet mask: 255.255.255.0
• Gateway: 192.168.1.1
• Primary DNS: 192.168.1.1
• Secondary DNS: 192.168.0.1

If I set it to "manual" and fill out:

• IP-Address
• Subnet mask
• Gateway and
• DNS Server

...with the information from above (exept IP address: 192.168.0.222), the connection won't establish and "Broadcast-Address" differs:

• Broadcast-Address: 192.168.0.255

Aim: I want to access my desktop ubuntu with my phone within the local network. Therefore my pc needs a static IP and the broadcast address is wrong, right?

I've solved my problem, by creating a fix-ip-rule (ger: "feste IP Adresse") for my pc within my router options. To do so, I've entered the gateway IP "192.168.1.1" in my browsers address bar and navigated to the "Network > LAN" Menu, where I've found the Option - and all without the need of console usage :)

I think there is something incorrect in your configuration (when it's set in auto). With the netmask and ip address you are using you should not be able to reach the ip 192.168.1.1 (gateway and primary dns), in fact you should not be able to reach any 192.168.1.x ip address. Try to ping to 192.168.1.1 and check if you have response.
