FIOS Router + RT-AC66R = Double NAT

[girdoom]

Hello All,

Just bought the RT-AC66R because my e-4200 died. So, now that I am getting into the additional features on the new router I am seeing issues because I am stuck behind my FIOS router. Basically what I am trying to do is set up DDNS (through ASUS) and AiCloud Smart Access.

I tried setting up my RT-AC66R's WAN IP as a DMZ host in the FIOS router, which didn't help. I am wondering if there is a way to configure the routers so that I set this up and running? Maybe some crazy amount port-forwarding could get me past this.

Has anyone set gotten past double NAT for double NAT and AiCloud?

Any assistance is appreciated.

Were you able to solve this issue? I am having the same problem.

On the ASUS if you go to system log, port forwarding - you should be able to see the ports / IP details you need to get to.

The issue I think you're going to have is that the WAN address you are using will be non-routable (192.168.x.x) so I'm not sure how you can publish an external IP to the DDNS service - as far as I can see you can't even tell it which address to use for DDNS, it will just pick up whatever is on the WAN interface.

Actually - I take that back. Doing some investigation of my own, I found this;

-Smart Access uses your Network Places (Samba) settings, including accounts, shared folders, and more. Once you enable it, you can access your Network Places (Samba) from any location at all times.
-Private IP AiCloud support will be added in future (for example WAN IP:192.168.x.x; 10.0.x.x; 172.x.x.x). As of this writing, you can setup port forwarding or DMZ to access private IP addresses remotely.

So if this is correct you just need to configure port forwarding for the Samba services to the computers you want to access remotely. There is a step-by-step walkthrough on port-forwardning here.

If you want to quickly prove the theory, I would use the other option (enable DMZ') for a test computer and prove you can access it remotely. I wouldnt leave it in the DMZ for an extended period of time for security reasons, but at least it will prove you can see the machine through the double-NAT setup. If this works, I'd take it out of the DMZ and configuring the machine specific port-forwarding.

Why do you not set up your AC66R as a AP? I had the same trouble, but as soon i selected to run it as an Access point all my double-nat trouble disappeared.

I hope i understand your issue correctly.
If so then this should be helpful to you...

This is how I have FiOS MI-424WR and external router (RT-AC66R) working together.

My FiOS router is a ACTIONTEC MI-424WR. If you have a different model simply substitute it whenever I mention the "MI-424WR".

IMPORTANT: If you are switching your "main" router (the one that gets address from FiOS, you MUST release IP address before you make another device with different MAC address your "main" router, or you will spend a long time with Verizon on the phone making them release and renew your IP lease!

1. The MOST IMPORTANT part is to have Ethernet enabled on your FiOS box! If you are getting internet through your FiOS router by way of Coax/MoCA then you are doing it wrong. You will still be limited by the FiOS router and its tiny NAT table and other shortcomings! If you do not have a SEPARATE ethernet line coming out of your FiOS box AS WELL AS a Coax cable, I highly recommend you call up Verizon and have them send someone out to activate the Ethernet port on your FiOS box and run a wire up to your router! It should cost you $100 exactly. If you are going through the FiOS router as a MoCA bridge than you are getting NO benefits of adding a better router to your network (except on LAN obviously)!

2. At this point you can configure MI-424WR to be a client of your router. You do not need DMZ or anything. Tell your MI-424WR to get a DHCP address from your router. Disable DHCP server and wireless and firewall. I am 99% sure this is all I had to do but it's been a long time.

3. At this point the Internet light on your MI-424WR should be orange instead of yellow. If it is orange even though Coax is plugged in, you are good to go.

4. Set up your RT-AC66R with the Ethernet wire direct from FiOS box to WAN port. Once this works and you have a DHCP address, now you may attach the MI-424WR. Attach ethernet cable to the one of the LAN ports on AC66R and the other end to Ethernet WAN on MI-424WR. You should see the internet light on MI-424WR change color.

5. If you have FiOS TV, turn on your TV and see if TV guide works. If it works, you are all set. If it doesn't, make sure you didn't mess up setting it up

The goal is to have RT-AC66U handle all the "router" functions. If you try to "split up" the work between AC66U and MI-424WR you will have problems. Your DDNS and AiCloud should work fine now, as well as better overall internet performance!

Some details (LED colors etc) might be slightly off because i am writing this from memory. I used to have a lot of trouble with MI-424WR and my routers before until I came up with this setup. It's been running like this for almost THREE YEARS now and works BETTER THAN IT EVER HAS.

I attempted to do this and called to have my ONT switch internet from coax to ethernet. They were willing to do this but stated the fios router still had to be primary to have the video on demand and other features of the set top boxes work. is this true? this essentially make my keep my ac66u in access point mode while i use the fios router grudgingly to drive my network.

Longtime lurker, first time poster. I have done this with my AC-66R and FIOS. I simply did the DDNS login/registration from the FIOS router itself and then opened up the relevant ports to forward to the AC-66R router that sits behind the FIOS router. Works just fine to access a Synology NAS and two webcams on the home network. My setup is Ethernet from ONT --> FIOS router WAN port --> Port 1 on on FIOS router to ASUS router WAN Port (ASUS router using hard coded IP address). All the other network equipment hook to a network switch that hangs off port 1 on the ASUS router. Channel guides work just fine, only thing that I don't get is the ability to use an iPhone or iPad app to program or use a channel guide since the settop boxes are on another segment. The FIOS router handles DHCP for the setuptop boxes (192.168.1.x/24) and the ASUS router handles the rest of the network equipment via DHCP (192.168.99.x/24).
