Hi so I'm from Calgary, Alberta and I have fiber internet through Telus. They set up a "fiber box" in my basement that connects to a router upstairs. They gave me some * actiontech router that only gives me 45 mbps wirelessly and also creates a double nat if I connect my router to it through pass through. So I disconnected there router and directly plugged in from the fiber box to my ASUS RT-AC68U and it works like a gem! Full 100mbps wirelessly all my IPTV stuff works and what not, its awesome!

But now my ISP calls me and says they are confused as to why they can see so many MAC addresses they tell me they should only see the 1 mac address of my router but it turns out they see every single one of my MAC address that is directly connected in to my router via ethernet.

What is going on? How do I fix this? Is there some sort of setting in me ASUS RT-AC68U that I overlooked or have forgotten to turn on?

Note my firmware is: 378.50 merlin asuswrt build

EDIT 1: Also they say all the other mac addresses they can see are requesting an IP address? or a connection or something?

<Language, please>

You ensured that the fiber box is connected to you WAN port and not a LAN port.

If you connect to a LAN port I can see all your systems requesting IPs directly from your ISP.

If you have any kind of pass though(NAT turned off/DHCP off/ect) on your router it should be switched off. By default, all routers should be set to act as routers and not switches.

You settings appear to be under Advanced - > WAN -> Internet Connection.

Its connected to the dedicated WAN port. When I go in to WAN settings under the Internet Connection tab under Basic config I have:

Enable WAN: YES
Enable NAT: YES
Enable UPnP: YES

Under WAN DNS Setting

Connect to DNS Server Automatically: YES


Those seem to be the only things turned on under WAN settings should I turn them off? Is there any sort of walk through websites from the RT-AC68U to turn it in to a modem? Or as you said I want to turn it in to a Switch? As a switch will it still give off wireless? sorry vaguely new.

Edit 1: Oh sorry under basic config it also says
Wan connection type: automatic IP

Your settings look perfect(well upnp is upto you. I have it OFF on all routers. It does not effect what your isp sees).

So you just have a Ethernet cable from the Fiber optic modem to the router and your systems on the routers 4 lan ports and wireless.

Can you please check what IP you are pulling on each system. If they are all within the 192.168.x.xxx zone it would appear everything is working fine.

I am not sure why your isp would see anything but your router and its single mac address(you can even change that in the settings, but it should not be needed for any reason. Some ISPs used to lock to the first computer activated and thus changing it to match a local computer used to have to be needed, bit it has been a long time since I seen any isp do this.).

If you at some point had computers connected directly to the fiber optic modem, they would have seen that machine.

How do I check the IP on each system? My 4 Lan ports are like so:

1: IPTV Set top box
2: IPTV Access point (3 other wireless box's connect to it)
3: OOMA Voip telephone service
4: A desktop PC

have about 6 other PC's connected wirelessly and about 15 other devices cell phones and such. (none of which seem to show there MAC address to my ISP) but all of the Lan ones do! And yes my Ethernet cable from the Fiber optic modem to the router. Nothing else has ever been plugged in to it except there actiontec one.

The ethernet cord coming from the fiber box in to the router is connected via Lan port 1 on the fiber box? Could that be a problem? Thats how the tech had it first set up though but looking on the back of the fiber box there is LAN 1-4 and then 2 other ports called POTS 1 and POTS 2. No clue what they are for...

But yeah they say they can see 6 devices.

1. a cisco device (which all of there TV box's and access points are cisco)
2. my OOMA

the rest they could see but could not confirm what they were.

Your IP of the computer fan be found in the control panel or with the command prompt and the command ipconfig /all
Other devices ips should be in the settings. Your router should also be able to log current connections.

You have quite a full network.

The LAN1 port is fine the POTS ports are for phones(not cellular, just normal old fashioned phones). It almost seems like you already have dual lans going if the fiber optic box has 4 ports it may well also be a router/modem in one. A computer on the LAN2-4 ports of that box may well be separated from the rest of your systems.

Please check the Administrative section to make sure it is not in access point mode or anything like that maybe. By what your ISP says it almost looks like HDCP is OFF, but that would be a strange default setting.

Thats what I asked my ISP about the fiber box only having Lan ports... They said it was normal and that with there Actiontec router they only see its mac address but with my RT-AC68U they see all my LAN Mac address's... so I have no clue at all.

Plus its insanely hard for me to even get any help on the matter from them... they just keep telling me to hook up there peice of shit that Cant even deliver the speed I pay for!

Administrative section says has: Wireless router mode (Default)

checked off.

How would I go about doing this? I can see all the IPs in my DHCP Leases tab. but how can I tell which one Im getting them from? And do you mean the WAN IP address for my router from my ISP or? and what do you mean by range? Sorry need more detail ahha

The DHCP lease tab should show all the IP's that have been assigned by the router. So anything listed in that tab should be from your Asus unit.
you WAN IP is assigned by your ISP and will normally not me in the 192.168.x.xxx range. By range I mean 192.168.0.xxx would be 192.168.0.1(router most times) - 192.268.0.254(255 being the broadcast address so not used by systems.)

so any 192.168.x.xxx assuming the first X is the same on all will generally be in the same range(but with different subnets it may not always be so, but that is not something you need to worry about.).
