ubuntu 20.04 SSH into a server that is connected to VPN

SSH Tunnelを使用し、サーバー側のSSH受け待ちを特定NIC(div,ip address)をしたが、SSHパケットはその特定NICから受けても、結局VPN接続が確立した際の、VPN特設ルートにつかまって、VPNに転送されてしまい、結局もとのNICからSSH発信元までもどってこない。 

 

The way beneath did not work on my case, of which many of solution suggested are quite the same as this. Perhaps the way might have worked but my assumptions or setting up might be worng in the way NOT this towork.
