Não há logs do UFW no syslog

Question

Estou usando aqui o UFW como uma proteção básica. Quando estou usando o wi-fi da faculdade eu recebo algum bloco UFW (o que é normal, porque o firewall está ON).

Mas, estranhamente, não estou recebendo nenhum log UFW em casa (costumava ser um pouco, mas agora não há blocos).

Aqui estão algumas informações sobre ufw status verbose

Status: active
Logging: on (low)
Default: reject (incoming), allow (outgoing), disabled (routed)
New profiles: skip

Há algo errado com meu roteador ou PC?

EDIT: Estou incluindo alguns logs de blocos do UFW do syslog:

Obrigado por me ajudarem.

    

Answer 1

Praticamente estes são os mesmos registros.

Tente com o comando

sudo ufw logging high 

Depois disso, a verificação será registrada em /var/log/ufw.log
