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 before and, despite what a couple users posted, it is actually not possible to get a passing score on ipv6-test because the R7000 stock firmware is filtering ICMP:  https://community.netgear.com/t5/Nighthawk-WiFi-Routers/R-7000-and-IPv6-Test/td-p/494908/page/2

 

This works fine if you flash XVortext Asus WRT firmware, but I can't use that due to broken QoS on IPv6.  This also proves it is a problem with the stock firmware.

 

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)

Re: IPv6 ICMP Filtered

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.

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

Re: IPv6 ICMP Filtered

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...

Hi Kwolf,

 

Please update your R7000 to the latest firmware v1.0.5.64.

Updating firmware is normally a good thing but from what i hear the IPv6 filtering ICMP/V6 packets is once again not fixed in the new release. Please someone correct me if i am mistaken.

Hi Jim769,

 

I would suggest to try the latest firmware and see if it has the same problem. I haven't not seen any feedback from other users that it has the same problem.

First and foremost i dont own a Netgear router, been there done that. I have not seen any feedback that says it has been fixed. They never fixed it for the last 3 years.

If the release notes don't include IPV6 in it's fixed list then I doubt it fixed itself.

Re: IPv6 ICMP Filtered

I have a Netgear R6400 on Firmware Version V1.0.1.6_1.0.4 .  Cox has fully implemented IPv6 here, but the Router is still showing ICMP as being filtered during testing, which means this router also has this issue, and it is not fixed in this most recent firmware version.  Netgear - you need to fix this.

Re: IPv6 ICMP Filtered

After talking with Netgear many times over this and there stance of filtering ICMP/V6 packets because they believe if they dont it's a security risk, i have come to the fact that all Netgear routers have IPv6 that does not work properly. Unless or until they STOP filtering these ICMP/v6 packets it will remain broke.

Re: IPv6 ICMP Filtered

Do all Netgear routers have this firmware bug?

Re: IPv6 ICMP Filtered

Yes because they keep filtering ICMP/v6 packets in there firmware firewall rules. Keep in mind this is a very simple fix they refuse to do. So as i have said many times if you want a true working native IPv6 use third party firmware if possible or invest in a router from another manufacture.

Re: IPv6 ICMP Filtered

FYI: Updated R6400 router to latest firmware released in the last few days (Firmware Version V1.0.1.12_1.0.11), and it is still filtering IPv6 ICMP.  The release notes also do not address this.

Re: IPv6 ICMP Filtered

Any way you can check if the 7000 has this same issue?  There no actual reason anyone should filter IPV6 ICMP.
