| To setup NAT on Ubuntu, see [[https://help.ubuntu.com/community/Internet/ConnectionSharing#Ubuntu_Internet_Gateway_Method_.28iptables.29|Ubuntu NAT]]. We'll add a short bit of instructions to the system to forward the ports as follows: {{{ #Port Forwarding Stuff: iptables -t nat -A PREROUTING -i eth0 -p tcp -d 216.249.119.[your ip] --sport 1024:65535 --dport 3389 -j DNAT --to-destination 192.168.1.2 iptables -t nat -A PREROUTING -i eth1 -p tcp -d 216.249.119.[your ip] --sport 1024:65535 --dport 3389 -j DNAT --to-destination 192.168.1.2 iptables -t nat -A PREROUTING -i eth0 -p tcp -d 216.249.119.[your ip] --sport 1024:65535 --dport 3390 -j DNAT --to-destination 192.168.1.3:3389 iptables -t nat -A PREROUTING -i eth1 -p tcp -d 216.249.119.[your ip] --sport 1024:65535 --dport 3390 -j DNAT --to-destination 192.168.1.3:3389 }}} NOTE: ALL OF THIS CAN BE FOUND BY TYPE "man iptables" from the command line in linux. |
In 2021 we are going to use pfSense as our router firewall. Set it up using the diagram above and the instructions in class. |
