AC68U DDNS Script Help

[cgi2099]

Hello everyone, just got a 68U and I am trying to set up a ddns for ftp access to my hard drive connected to the router. My isp is configured using a double NAT so my router is saying invalid ip, and they will not give me my own public IP. I am using the most current version of the merlin firmware and I see there is an option to use a script to achieve this behind a double nat. I guess basically I need the router to retrieve my public IP from an external site other than the WAN IP on the router?

Could someone help me out with this script, I have very little experience with coding, so I would need a cut and paste solution?

I have figured out how to export the firmware to get the the script folder.

My Setup is a SurfBoard 6183 and a AC68U.

DDNS won't help with your double-NAT problem. You need to be able to configure the upstream NAT device to do port forwarding to your router. Without that it will never work, DDNS or not.

Dang that sucks! Do I have any other option to be able to access the hard drive connected to the router remotely? Trying to use it kinda like a personal cloud until I can get my NAS.

You do not have a modem (or any other box from your provider) connected to the wall and then to your router?

I can see that newer fw versions probe extrernally and know real IP. Do not know your version. But, try to ssh into a router and type:

nvram show | grep realip_ip

Does it spit a public address? But, still, this does not help you as you may be behind another private IP address in the middle.
