I have created a very simple tool to help configure and forward ports for Multiple Public IPs on a DD-WRT enabled router. The biggest issue, in my opinion with DD-WRT and Multiple Public IPs is the requirement to use the commands to manually add all the ips. This can be tiresome when you have many small changes to make, want to add new port forwards, remove ips, etc. So I put together this simple tool.
You can find it on its dedicated page along with all it’s documentation.
