IPv6 incoming traffic blocked by router

[valder]

Outgoing IPV6 traffic is fine, but am unable to receive IPV6 traffic through my router.   My ISP suggest that ther might be a firewall setting blocking it, but I do not see any firewall settings in the router.

Also, IPV6 traffic within my local network works fine.

what is the IPv6 subscription type from ISP? Did you receive a valid IPv6 WAN address on the Internet port?

[valder]

I'm not sure what your asking for with Subscription type.  But I got a valid IPV6 address for my server and was even able to add it to the AAAA record for my IPV6 Address of my server without an issue.

My Domain name is qtek.us

IPV6 address of my Server: 2604:5500:810:2fc::1

Router's IPv6 Address On WAN

2604:5500:810:2:a263:91ff:feca:d519/64

Router's IPv6 Address On LAN

2604:5500:810:2fc:a263:91ff:feca:d518/64

I am trying IPV6 ping test from inside the router from my server and get no response.  Also, I can get to my site from within the router by using the qtek.com url, but from outside the router I cannot.

.... and the ISP is Webpass.

Go to Advanced > Setup > WAN Setup > Check "Respond to ping on Internet Port"

This is already chosen. along with Disable IGMP Proxying.

Also, this is not a ping issue, I am using ping as a tool to test the path.  It is IPV6 that is being blocked by the router.  I have no problem getting to my qtek.us server from within my person network inside the Router.  The ISP says that some routers, have a firewall that blocks IPV6 traffic unless you turn it off.  I see nothing like this in this router.
