Pergunta: como você configuraria a rota padrão? [fechadas]

Question

Eu tenho uma pergunta que comando você usaria para configurar a rota padrão? Quero dizer, eu tentei: ping 192.168.3.50 PING 192.168.3.50 (192.168.3.50) 56(84) bytes of data. 64 bytes from 192.168.3.50: icmp_seq=1 ttl=64 time=0.058 ms 64 bytes from 192.168.3.50: icmp_seq=2 ttl=64 time=0.030 ms 64 bytes from 192.168.3.50: icmp_seq=3 ttl=64 time=0.030 ms

Em seguida, tentou configurar o gateway padrão:

ip route add default via eth3 peer gw 10.0.3.142 dev eth0

mas não funcionou. : (

Aqui está minha configuração de rede:

Answer 1

Para tornar isso a rota padrão do sistema, faça o seguinte:

ip route add default via 10.0.3.1

Mas , se você já tiver outro gateway padrão, faça o seguinte:

ip route replace default via 10.0.3.1

Para substituí-lo.
