I have been messing with enabling LAN side ipv6 on my gateway. I was doing some performance testing that began with ipv6-test.com and their side by side ping test of ipv4 and ipv6.
I noticed both were timing out with 100% packet loss.
all it took was disabling this
in the routers firewall to allow ipv4 to to start properly pinging.
IPV6 timed out unless I disabled windows firewall. That was the only way I could get it working. I had assumed these were the associated rules, yet as you can see - both ipv4 and ipv6 are enabled.
if i go inside the ipv6 rule, it shows echo as being enabled
so this is where my networking acumen comes to a halt more or less.
Can someone point me to the hang-up? I havent added any non out of the box windows firewall rules afaik, so whatever is superseding or preventing is beyond me.
Scope tab shows as follows. Seems identical to its ipv4 counterpart which is allowing ipv6-test to ping ipv4 (presuming these are in fact the relevant rules but i believe they are)
