Hello, to everyone who is having a pppoe problem, I kindly ask you to follow the steps below, as it resolved the issue of fullconenat and also of dns in quic in adguard.

I found the problem related to pppoe, here’s how I fixed it.

I was getting this error “DHCP packet received on eth1 which has no address”

this is the fix

echo "except-interface=eth1" >> /etc/dnsmasq.conf
service dnsmasq restart

After that, update the fullconenat file to the data below.

#!/bin/sh /etc/rc.common

START=99

set_rules() {
    iptables -t nat -I POSTROUTING -o $1 -j FULLCONENAT 2>/dev/null
    iptables -t nat -I PREROUTING  -i $1 -j FULLCONENAT 2>/dev/null
}

clear_rules() {
    local ifaces=$(iptables -t nat -nvL POSTROUTING|grep FULLCONENAT|awk -F' ' '{print $7}')
    for item in $ifaces; do
        iptables -t nat -D POSTROUTING -o $item -j FULLCONENAT 2>/dev/null
        iptables -t nat -D PREROUTING  -i $item -j FULLCONENAT 2>/dev/null
    done
}

find_wan_gw()
{
    local wan_list=$(ubus list|grep interface.|grep -v -E 'lan|loopback|4|6')
    for item in $wan_list; do
        local ubus_data=$(ubus call $item status)
        local up="$(echo $ubus_data|jsonfilter -e '@.up')"
        [ "$up" = "true" ] || continue

        local gw="$(echo $ubus_data|jsonfilter -e '@.l3_device')"
        [ -n "$gw" ] && set_rules $gw
    done
}

stop() {
    clear_rules
}

start() {
    if [ "$(uci get fullconenat.global.enable)" = "1" ]; then
        local ifaces=$(iptables -t nat -nvL POSTROUTING|grep FULLCONENAT|awk -F' ' '{print $7}')
        [ -z "$ifaces" ] && find_wan_gw
    fi
}

located at /etc/init.d/fullconenat

After that everything works perfectly.

Follow the correction link.

another fix is ​​regarding dns in quic in Adguard, to be able to use it you have to place the commands below in /etc/sysctl.d/10-default.conf and/or /etc/sysctl.conf

Below are the corrections.
