examples of SNAT, DNAT with iptables for Advantech, Conel routers, with comments (probably will work on other routers where iptables can be manipulated, care needs to be taken on applying these commands after reboot)

Some examples of SNAT, DNAT with iptables with comments

mainly used in start-up script

masquarade all outgoing packets to be WLAN0 IP

iptables -t nat -A PREROUTING -s 192.168.1.2 -i eth0 -j MASQUERADE
