I want to use a Linux Maschine hosted in another Datacenter to forward traffic to my internal network. Basically I want to use the Linux Maschine as a Gateway to forward the traffic.
For example I want to access external_ip:80 and forward it to internal_wan_ip:60001, on my firewall(fortigate) the port will accept connection only from the external_ip and its mapped to the right server and right port.
Whats the best approach to this?
