IPv6 ICMP Filtered

Doing the test on http://ipv6-test.com/ results in "Filtered" for ICMP, even if you disable "port scan and ddos protection" and enable "respond to ping on wan port".   The problem was discussed bef...

    As I have mentioned in other threads here I worked with Netgear for months last year trying to get them to simply stop filtering the ICMP/v6 packets by changing a firewall rule and they have refused saying its a security risk. I don't understand why the network engineers at Netgear don't get that these packets must NOT be filtered for IPv6 to work properly. 

     

    Anyways it became like beating a dead horse and I finally gave up returned the Netgear router and bought an Asus RT-AC3100 and all problems were instantly solved. So the bottom line I doubt there will be any fix for this in the foreseeable future and IPv6 will continue not to work the way it was intended for Netgear routers. If you want or need a router that has real working IPv6 then you will need to buy from a different manufacture.

Is this ever going to be fixed?  It's been an issue on every firmware version, even the latest "pulled" one (1.0.6.40)

In order to fix it you'd first have to admit it's a problem.

    Thanks m8, I'll keep ASUS in mind for my next router purchase.

     

    Honestly, if the Netgear engineers are too dense to understand the extremely basic FACT that ICMP in IPv6 is a fundamental requirement of the protocol, I wonder what else is overlooked in the router firmware.  This certainly doesn't bode well for future firmware releases.  No wonder the past few firmwares have been completely botched, with this caliber of "engineers" working on them...
