I was following this post https://www.digitalocean.com/community/tutorials/how-to-forward-ports-through-a-linux-gateway-with-iptables to set up port forwarding.
Under Firewall network details:
In the Tutorial, Private IP Address: 192.0.2.15
For my setup, Private IP Address: DYNAMIC
The Private IP address of the firewall doesnt come anywhere untill the last command,
sudo iptables -t nat -A POSTROUTING -o eth1 -p tcp --dport 80 -d 192.0.2.2 -j SNAT --to-source 192.0.2.15
How do I replace this everytime my firewall’s private ip address changes?
