Custom URL to access outside the system on Non-Production set-up

Hi All,

I have installed a local installation of a Non Production environment. The environment is up and running on a temporary licence for now (awaiting a perm lic from Appian). I have followed on the basic instructions to set up this environment on my local machine, not connected to a domain ( I used the loopback address as fqdn - 127.0.0.1). I am able to open the consoles after the startup of the instance with link http://127.0.0.1/suite/tempo but would like to know if I can do something that I can use this instance even from outside the network. I want to set up a custom URL like (http://www.exampleabc.com:8080/suite/tempo) . I need this set up, because since I am not connected to a domain, whenever I change my laptop to different network, the instance may not work, because of the new IP address. To avoid this, I'll leave my laptop turned on and access the instance from outside the network when needed. 

Please advice or guide on the above query.

Regards,

Hemanth
