Hi there, I'm running OpenWrt 21.02.0 r16279-5cc0535800 on my router.
My ISP provide an /60 prefix, but for some reason, I need to use the cable modem as the main router.
The modem doesn't provide downstream PD so I can only see an /64 address on the 'wan6' interface.
I setup the IPv6 relay as the wiki guide says:
config dhcp 'lan' option interface 'lan' option start '100' option limit '150' option leasetime '5m' option ra 'relay' option dhcpv6 'relay' option ndp 'relay' option ndproxy_routing '0' option ndproxy_slave '1' list ra_flags 'none' config dhcp 'wan6' option interface 'wan' option ignore '1' option ra 'relay' option master '1' option dhcpv6 'relay' option ndp 'relay' list ra_flags 'none'
Then I connect My PC to the openwrt router, actually it got an Global Address. But I can't ping any IPv6 address except the gateway address (the Link-local address of router's lan interface begin with fe80). Even can't ping the GUA and Link-local address of wan6 or cable modem.
