NAT from internet/firewall thru a Ubuntu computer, to another network and device. (routing)

  • 772

(Ubuntu) computer has two network interfaces: (and is not sunning iptables)

wlx1cbfce8bd2bd: inet 10.1.1.129 netmask 255.255.255.0

on this network, there is a device:  10.1.1.10 - with a UDP port 10000 that I wish to publish to the internet.

the second interface is....

enp4s0: inet 192.168.1.80 netmask 255.255.255.0 (this is connected to Fortigate Firewall)

Fortigate LAN IP is:  192.168.1.1 

I wish to enable somebody to connect to the UDP port 10000 of the 10.1.1.10 device from the internet.

I do know how to set up NAT(Virtual IP) and IP4Policy to forward traffic to 192.168.1.80  - but I do not know how to do it to 10.1.1.10   

I assume I need route(s) on Fortigate, as well as on my PC (192.168.1.80)  to achieve that.

I have no problem NATting from the firewall to the PC's 192.168.1.80 address and some port, but how should this traffic be forwarded to the 10.1.1.x network?

routing
