This page is used to map specific private IP to specific WAN IP alias.
If you have "a group of IP Addresses" and want to apply to the router, please use WAN IP
alias function to record these IPs first. Then, use address mapping function to map specific
private IP to specific WAN IP alias.
For example, you have IP addresses ranging from 86.123.123.1 ~ 86.123.123.8. However,
your router uses 86.123.123.1, and the rest of the IPs are recorded in WAN IP alias. You want
that private IP 192.168.1.10 can use 86.123.123.2 as source IP when it sends packet out to
Internet. You can use address mapping function to achieve this demand. Simply type
192.168.1.10 as the Private IP; and type 86.123.123.2 as the WAN IP.
