Iptables não fazem balanceamento de carga

2

Eu consultei vários tutoriais para obter balanceamento de carga em duas conexões de internet. No entanto, todo o tráfego continua sendo roteado pela rota padrão com a métrica mais baixa e não consigo entender por que

iptables -t nat -F
iptables -t mangle -F
iptables -F
iptables -X

ip rule delete from all fwmark 0x1
ip rule delete from all fwmark 0x2

ip rule flush
ip rule add lookup main priority 32766

iptables -A PREROUTING -t mangle -j CONNMARK --restore-mark
iptables -A PREROUTING  -t mangle -m mark --mark 0x0 -m statistic \
         --mode nth --every 2 --packet 0 -j MARK --set-mark 1
iptables -A PREROUTING  -t mangle -m mark --mark 0x0 -m statistic \
         --mode nth --every 2 --packet 1 -j MARK --set-mark 2
iptables -A POSTROUTING -t mangle -j CONNMARK --save-mark

ip route flush table wlp3s0
ip route flush table enp0s20u2

ip rule add fwmark 1 lookup wlp3s0 priority 1000

ip route flush cache

rota ip:

ip route

ip route list todos os quadros wlp3s0

default via 46.37.116.1 dev wlp3s0 
46.37.116.0/23 dev wlp3s0  scope link

ip route list toda a tabela enp0s20u2

default via 192.168.42.129 dev enp0s20u2 
192.168.42.0/24 dev enp0s20u2  scope link

regra ip

0:  from all lookup local 
1000:   from all fwmark 0x1 lookup wlp3s0 
1000:   from all fwmark 0x2 lookup enp0s20u2 
32766:  from all lookup main
