Problems forwarding public address to AC66U

[Ethered]

Hi,

I've been trying to forward the public address from my ISP-router to my AC66U, but keep getting the error message saying "No compatible connection found".

The ISP-router is a Thomson TG789vn, the LAN-range is 10.0.0.0/24 and DHCP is enabled. I have a fiber connection from the ISP using IPoE, and is connected in the WAN-port from the fibre converter.

The Asus AC66U has 192.168.1.0/24 as the LAN-range, and the WAN-port gets an IP-address correctly from the Thomson. Both the Asus and the Thomson sees the link as active, and things looks correct.

Even so, the Thomson keeps giving me the same error message, after repeatedly restarting both devices etc. I've tried connection my laptop directly and then assigning, and still get the same message.

Hopefully someone has some thoughts as to what may be the problem.

If the Asus is doing all the routing etc, then you could just set it up as DMZ in the Thompson. This way the Thompson just passes everything onto the Asus and the Asus does everything from there. As long as you have the firewall enabled on the Thompson that is.

There is a guide here: http://help.telecom.co.nz/app/answers/detail/a_id/20201/~/dmz-mode---thomson/technicolor-modems

If DMZ doesn't work, then try the link below. It describes how to port forward with two NATs. Sometimes you have to use alternate port numbers depending on the router.

That is what I am trying to do, where my Asus doesn't show up in the devices list.
