If you require more than sixteen NAT rules, insert the remaining rules into the Startup
Script. The Startup Script dialog is located on Scripts page in the Configuration section of the
menu. When creating your rules in the Startup Script, use this command for IPv4 NAT:
iptables -t nat -A napt -p tcp --dport [PORT_PUBLIC] -j DNAT
--to-destination [IPADDR]:[PORT_PRIVATE]
Enter the IP address [IPADDR], the public ports numbers [PORT_PUBLIC], and private
[PORT_PRIVATE] in place of square brackets. For IPv6 NAT use ip6tables command with
same options.:
ip6tables -t nat -A napt -p tcp --dport [PORT_PUBLIC] -j DNAT
--to-destination [IP6ADDR]:[PORT_PRIVATE]
If you enable the following options and enter the port number, the router allows you to
