OpenWRT tricks

TIM Live Brazil Fiber (FTTH)

It uses PPPoE like the VDSL, but you need to set the VLAN.

Unlike the VDSL connections, for FTTH connections you need the VLAN ID 100.

Unfortunately you can't use the Luci GUI interface. Tested with OpenWrt 21.02.

Edit /etc/config/network, specifically the find wan and wan6 interfaces:

config interface 'wan'
        option proto 'pppoe'
        option password 'guest'
        option ipv6 'auto'
        option username 'guest'
        option device 'eth0.2'
        option ifname 'dsl0.100'  ## This is essential

config interface 'wan6'
        option proto 'dhcpv6'
        option device 'eth0.2'

IPv6 needs more work, since my connection does not have it enabled, trying to enable inside the wan6 prevents me the connection with PADO timeouts.

Be aware that device 'eth0.2' can be different for your router model.

Slow PPPoE

If you're having slow throughput using PPPoE, specially under the FTTH connection above, enable Software flow offloading inside Firewall settings.

It will make QoS SQM to not work, but since I have plenty bandwith now, I just disabled it.

Blocking URLs at dnsmasq

uci add_list dhcp.@dnsmasq[0].address='/'
uci commit dhcp
/etc/init.d/dnsmasq restart
