如何从同一局域网内的另一台计算机访问 Big Sur 上的 localhost:4200（Angular App）？

Question

screencapture : linksys port-forward table

My case is listed as below :

• The client computer and the server computer are on the same lan where the wifi router is : linksys model#ea6200
• The client computer can ping the server computer(where the server's OS is Big Sur 11.4 and its IP is 192.168.1.149)
• The server is already listening to http://localhost:4200 , which is an Angular application .
• But , when I type http://192.168.1.149:4200 in the client's browser, the site can't be reached from the client's computer .
• I have checked that the Big Sur's firewall is off.

My Question is :

1. What else should be further set so that the site on the server computer can be reached from the client's computer ?
2. Should I consider to make some configuration on the linksys port forwarding policy?

Thanks.

Answers from "NSteinbusch @ https://discord.davidbombal.com/ " :

• this is an Angular issue rather than networking issue ;
• by default angular only listen on local interface 127.0.0.1 ;
• By using the cmd of “ng serve -- host 0.0.0.0” instead of simply typing “ng serve” to start the app, the client PC should be able to reach the Angular app of the server by http://192.168.1.149:4200/
• By this method, the server will listen to all available interface, so your Ethernet NIC or Wi-Fi NIC as well.
