dyndns Internal ports

[dams09 0]

Hello,

I have a problem that I can not understand.

I explain you my infra

Router sysnology with the VPN airvpn configured on it in openVPN

In my LAN, a synology with several services like plex or bitwarden

I configured ports from my client interface with airvpn with dyndns and it works well for example toto.airdns.org: 123456 goes well on my DSM service on my synology on the port 5001 so the routes are good.

Now I have a domain name of my own that I would like to use to connect to my synology without having to put the airvpn address, so I can make a CNAM alias toto.airdns.org => toto.mydomain.com but I can't put the port. So it doesn't work.

I tried to change the port configuration on the airvpn platform in "internal ports" to port 443 (ports used in https) and I did the same route as for port 123456 but it does not work, the service always responds on port 123456 but not on port 443

A good soul could help me?

Thank you in advance.

DNS doesn't know ports. Use toto.mydomain.com:12345 to connect to toto.airvpn.org:12345.
