Problems accessing to a RDS through a Bastion Host from a local K3s

I'm trying to build a local Kubernetes with K3s and I'm having problems to access to my RDD that is situated in the private Area of the VPN.

For now, I'm trying to deploy a Passbolt (https://artifacthub.io/packages/helm/cnieg/passbolt) and I'm following the steps to use my own database. Before the creation of the service, I've previously bind the port with the command:

ssh -i key.pem -L 1223:db:3306 user@BASTION -N -f

The service that I'm trying to use is:

apiVersion: v1
kind: Service
metadata:
  name: db-mysql
spec:
  selector:
    externalName: 10.0.2.2
    type: externalName
  ports:
  - protocol: TCP
    port: 3306
    targetPort: 1223

I'm getting this error:

Exception: There was a problem connecting to the database: SQLSTATE[HY000] [2002] Connection refused

Same if i try to use 127.0.0.1 instead of 10.0.2.2

Thanks!

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
