Hi folks, I have found a solution on https://www.joewein.net/info/sw-iptables-full-cone-nat.htm, which works fine for a single internal IP address. However, I am struggling to configure "full cone" NAT for multiple internal IP addresses using iptables. I have tried the following rules, but they do not seem to work: iptables -t nat -A POSTROUTING -o eth0 -j SNAT --to-source 192.168.2.170 iptables -t nat -A PREROUTING -i eth0 -j DNAT --to-destination 10.0.0.1 iptables -t nat -A PREROUTING -i eth0 -j DNAT --to-destination 10.0.0.2 Could you please advise me on how to configure "full cone" NAT for multiple internal IP addresses using iptables? If this is impossible, are there any alternative solutions to achieve this goal?
