- A basic configuration is easy to setup. You can just follow guides / official documentation.
- You need to make sure IP forwarding is enabled. You can do this by running sysctl -w net.ipv4.ip_forward=1 or making it permanent by editing /etc/sysctl.conf and setting
net.ipv4.ip_forward = 1
- Also you need to enter such a forwarding rule:
iptables -t nat -A POSTROUTING -s 10.100.0.0/24 -o enp1s0 -j MASQUERADE
