Our company have two working location - office & datacenter

two working location have own boardband line to connect internet - user in office use office boardband line to connect internet , user in datacenter use datacenter boardband line to connect internet .

We have a linux server in datacenter , it connects internet directly .

Now , if I want a user in office connects internet via this linux ( in datacenter ) , I need to setup router in this server ? what I need to do ?

This is a very broad topic well beyond the scope of a forum thread.

A web search for "linux router" will turn up many articles about this subject. There are also a number of articles at the LQ Wiki.

I suggest that you read some of them and then come back with any specific questions you have then.

You could always use iptables, which as far as I know, most (if not every) Linux distribution has or can be installed.

This might help you.

You will need the same configuration (except network interface configuration) as datacenter Linux, on your office Linux server.

1. Allow network traffic between interfaces using sysctl.conf
2. Configure the firewall to NAT internal traffic using iptables.
