strongswan IKEv2 disable reauth (NetworkManager)

Question

Eu configurei uma conexão VPN usando o IKEv2 para o meu roteador Draytek, que funciona por uma hora, em seguida, apenas desconecta (e não consigo reconectar a menos que eu reinicie). Pelo que encontrei até agora, isso pode estar relacionado à recriação de IKEv2 que (de acordo com o link ) não funciona ao usar o NetworkManager .

Eu não posso provar que é o problema porque meus logs do NetworkManager não dizem nada sobre rekeying, mas se eu me conectar à VPN às 12:26:46 e eu for desconectado às 13:26:43, então eu acho que é bastante óbvio .

De qualquer forma, não consigo descobrir como configurar o registro de conexões strongswan do NetworkManager e nem sei onde desativar o rekeying (reauth) para essas conexões. Alguém pode me dizer isso?

Usando o openSUSE Leap 15

EDITAR: syslog como solicitado nos comentários: link

EDIT2: syslog do roteador: link Eu só o filtrei pelo tempo, então é mais ou menos o mesmo que os logs do meu computador. Eu não vejo nada sobre a desconexão da VPN por volta das 13:26, então coloquei todos os logs do roteador a partir daquele momento. Havia 3 clientes se conectando com VPN para roteador - bartek, piotr e filip, estamos olhando para filip (bartek estava se conectando com Shrew VPN, que funciona sem problemas e piotr estava usando IKEv2 com strongSwan também, não foi desconectado ao mesmo tempo como eu, mas seria desconectado, eventualmente, como ele está usando a mesma configuração que eu)
