Hello,

my Archer MR550 is behind a CGNAT IPV4 address, so began to use IPV6 to make my Pfsense Wireguard failover connection working.

It works well with my primary fiber connection, but no luck with my Archer (ISP : Free Mobile).

To troubleshoot things, I first enabled ping from remote in system tools in admin panel, but MR550 doesn't respond from its IPV6 public address (and neither IPV4, but it's normal because of CGNAT).

I even tried to disable IPV4 and IPV6 firewall.

Does anybody have an idea ?

Thank !
