Model: Archer AX10  
Hardware Version: V1
Firmware Version:

I have the Archer AX10(US)_V1.2_201230   The latest firmware.  I am ONLY using IPV4 internet and do not really use IPV6.  The router interface show that the router itself has an IPV6 address

 

I have a test enviroment with VOIP phone Yealink and server windows 2012. The windows server run Dhcp the router TPlink Ax10 have SIP APG off Upnp off only 1 port forwarding to server at 443 for VPN via SSTP.

 

Port scan from a IPv4 internet was fine only 1 port open 443 when I run port scan.

However when I run the port scan from a IPV6 device, sudden the port scan showing port 21 80 443 554 1723 all open on my IP. The router has remote management off no FTP running anywhere I can see VPN on router also off. Upnp off so nothing should be able to punch hole and open port. I am at a lost.

 

This is something weird with the router not blocking it own IPV6 I think.

Never mind guys false alarm, figured out that it is not router but possibly something to do with an ONT.  Thank you for explanation.

@Net_Guy 

 

Have you disabled IPv6 form the router menu ? Try that if you haven't and see if any difference:

Yeah, my settings there (IPv6 LAN) are the same as yours. My screenshot is just an example for disabling IPv6 Internet.

For the Assigned Type options you can read here:

Have a look at this thread as well.
