with reference to the photos (https://www.dropbox.com/sh/gi80qmyjcdwl1kb/AABVIkCbEq3s6T2pelA2oFRga?dl=0), the image - "server_hosting(0.0.0.0:8080).png" shows that the server is successfully hosted on network without looping.
I browsed through the forum and realized some other users are also facing this problem (https://biostar.usegalaxy.org/p/5044/). After which, from the answers suggested, i went ahead with iptables firewall configuration and in the second image - "IP_TABLES_FIREWALL.png" shows the firewall settings i believe.
I do not really understand the result from the second image but my problem here is...
I want to let other users in my network to access the Galaxy which is hosted on my laptop. And for them to access, they have to type 0.0.0.0:8080 ?
