Open up localhost port to outside world

Question

I have a http service running on localhost port 8080 on a centos 7 machine. Is there any way I can route / port forward incoming and outgoing traffic through my external interface. So, mapping 127.0.0.1:8080 to <my external ip address>:8080?

I'd also like to do the same with https if possible as well.

I don't have access to the application code, so would prefer an iptables / port forwarding solution if possible.

Does this answer your question? How can I forward requests from my web server? — Gerald Schneider, Jun 24 '22 at 11:37
Or you could just bind it to the external interface as well ... — Gerald Schneider, Jun 24 '22 at 11:37
I don't really have the application code available, so was wondering if i could do something with iptables — WhatTheWhat, Jun 24 '22 at 11:39
@GeraldSchneider We shouldn't encourage people to expose localhost, mapping to external is the right way to go so it can be separated from internal work — Chopper3, Jun 24 '22 at 11:39

The REDIRECT target is probably the answer:
