Please try exactly(!) the following config:


config interface 'loopback'
	option ifname 'lo'
	option proto 'static'
	option ipaddr '127.0.0.1'
	option netmask '255.0.0.0'

config globals 'globals'
	option ula_prefix 'fdcc:f702:84dd::/48'

config interface 'lan'
	option type 'bridge'
	option proto 'static'
	option ipaddr '192.168.2.1'
	option netmask '255.255.255.0'
	option ifname 'lan1 lan2 lan3 lan4'
	option ip6assign '64'

config interface 'guest'
	option type 'bridge'
	option proto 'static'
	option ipaddr '192.168.20.1'
	option netmask '255.255.255.0'
	option ip6assign '64'

config interface 'modem'
	option proto 'static'
	option ifname 'wan'
	option netmask '255.255.255.0'
	option ipaddr '192.168.1.101'

config interface 'wan'
	option ifname 'wan'
	option proto 'pppoe'
	option username 'adsl at alice6.it'
	option password 'IPV6 at alice6'
	option ipv6 '1'

config interface 'wan6'
	option ifname '@wan'
	option proto 'dhcpv6'


Provide the output of:


ifstatus wan
ifstatus wan6


Please do package capture on the router using tcpdump and the wan interface at the time you bring up your ppp connection:


tcpdump -i wan -s 65535 -w /tmp/pppoe-connection.pcap
