I’m trying to set up IPv6 on my new ASUS RT-AX86U running Merlin 386.2_6. My ISP is a local city owned fiber (Fort Collins Connexion). So far all they can confirm is that that support IPv6 but have been no help in providing any setup information. I’m not sure their tech support even knows how. I’ve tried all the different modes in the router and the only one that works is passthrough which I’ve heard is not the best option. Native doesn’t work at all. Is it ok to use passthrough? Any ideas?
