Assuming the server is a Linux system the task can be accomplished with ip forwarding and iptables (masquerading). The are several articles that provide guidance but the best, in my opinion, is Naturally, you need to weed out the Arch-specific stuff.

However, I avoid home-rolling routers from existing systems with other purposes. I like a dedicated system and there are great router/gateway/firewall distros available. My preference is pfsense.

My topology is very simple

Internet ---> Linux Server -----> Linux server 1

I disable the iptable in linux server, but when I try to update or install any up from linux server 1 to internet I dont have access.
