port forwarding from the NAS through VPN to another server on OpenVPN client side

[Bjorn]

Hi there,

I've set up successfully DDNS + OpenVPN on my Synology DS215J / DSM 7 . Internet Access "on the go" is working well.

Additionally I want to route specific ports through the NAS to a server, which is connected through the OpenVPN. Meaning: I want to call DDNS:5xxx, which should be tunnelled to a server behind the VPN. Port forwarding is enabled on the router, where the NAS (DS215J) is connected, but whatever I do, port 5xxx is not "open".

Is it possible to let port 5xxx be accessible through the VPN (or not)?
If so, I was not yet able to find out how.

DS215J is using DSM 7.

Not sure I understand what you’re trying to do, but isn’t this particular server accessible (Provided that you’ve allowed LAN access on the VPN setup page and the firewall if any) since you’re already on your LAN when you use your VPN?

Thank you, got it to work: issue was, that I was expecting TCP port forwarding through the VPN, which was setup with UDP.
