原生教育网， openwrt ipv6 配置有问题，麻烦大神进来看一下

学校是 pppoe 拨号，然后 wan lan 口都能获得正常的 ipv6 地址，可是电脑连接上路由器上就没有 ipv6 访问权限，不知怎么解决，希望大神能够解决啦这是 dhcp 配置 config dnsmasq option domainneeded '1' option boguspriv '1' option filterwin2k '0' option localise_queries '1' option rebind_protection '1' option rebind_localhost '1' option local '/lan/' option domain 'lan' option expandhosts '1' option nonegcache '0' option authoritative '1' option readethers '1' option leasefile '/tmp/dhcp.leases' option resolvfile '/tmp/resolv.conf.auto' option localservice '1'

config dhcp 'lan' option interface 'lan' option start '100' option limit '150' option leasetime '12h' option ra 'hybrid' option dhcpv6 'hybrid' option ndp 'hybrid' option ra_management '1'

config dhcp 'wan' option interface 'wan' option dhcpv6 'hybrid' option ra 'hybrid' option ndp 'hybrid' option master '1'

config odhcpd 'odhcpd' option maindhcp '0' option leasefile '/tmp/hosts/odhcpd' option leasetrigger '/usr/sbin/odhcpd-update'
