I have gitlab server installed in a server (local server) which contain private ip address only. Now I want to access this gitlab from internet using port forwarding process. I do have gateway server which have public ip as well as private ip. Can any one help how to access local server for git using gateway server from internet. I tried using prerouting/postrouting rules in iptables of gateway server but no luck.

Either you need a VPN on the gateway server, or port forwarding + NAT, or a tunnel. [SO](https://stackoverflow.com/q/4717426/7976758), [Google](https://encrypted.google.com/search?hl=en&pws=0&q=expose+internet+server+local+address). – phd Aug 14 '17 at 13:19

`no luck` is not enough. What kernel version is on gateway? How did you configure `iptables`? Is forwarding enabled? Have you read [instructions](https://serverfault.com/a/140626)? Have you tried to watch packets with `tcpdump` trying to debug at what stage packets are dropped?… – phd Aug 15 '17 at 10:20
