Configure localhost to use DHCP IP address

Question

I have a local server Wildfly and I have a test application which I can access:

http://localhost:8080 works.

Now, I have comcast Xfinity with a modem (no additional router). I am working on CentOS 7. It looks like my internal IP address assigned by the modem is following:

[abigail@localhost ~]$ hostname -I 10.0.0.17 2601:9:500:ae7:4637:e6ff:fe40:74f2 I tried to access http://10.0.0.17:8080, but I can't. The website is not accessible. To do this, do I need to configure port forwarding in the modem? I did that but it still doesn't work. In the modem, I added one entry in the 'port forwarding' panel.

Port8080 TCP/UDP 8080 8080 10.0.0.17 Where I am doing wrong？

Edited for more info.

abigail@localhost ~]$ traceroute comcast.com
traceroute to comcast.com (69.252.80.75), 30 hops max, 60 byte packets
 1  10.0.0.1 (10.0.0.1)  0.700 ms  1.488 ms  1.769 ms
 2  73.170.240.1 (73.170.240.1)  19.791 ms  20.272 ms  20.395 ms
 ...

More info from the modem's configuration page:

WAN IP Address(IPv4):73.170.241.242
WAN Default Gateway Address(IPv4):73.170.240.1

If a network service is reachable via 127.0.0.1/localhost only, it is most likely configured to accept connections only on 127.0.0.1. To change this configuration, please refer to the server’s documentation. I’m not familiar with Wildfly, but it looks like you want something like this:

<interface name="public">
  <any-address/>
</interface>

Since you’re trying to connect via your local network, the modem isn’t involved at all. Unless you want to expose your service to the internet, you should remove the port forwarding you configured.
