Ok, we continue there i suppose, i will post the final answer later when we got it fixed. @moderator perhaps we can change the title to, ISP, Bridged, Router (605), OpenVPN Server in Omada

  @IIIdefconIII 

perhaps maybe another support engineer is willing to jon this conversation before pulling the last hairs out

  @IIIdefconIII 

What I would do in your place would be to disable all unnecessary configuration (ACLs, Port Forwarding, DMZ/VPN servers), delete curren Omada VPN server and create brand new, from scratches. with some random port.

I would also use some other device as well to test the connection - like PC or 2nd phone.

I don't think there are any more advanced logs on router's side in terms of VPN connection unfortunately :( Which means the investigation of an issue is hard.

Since your NAS' VPN works the I assume there's nothing wrong with ISP's services nor the IP.

Cheers

hi man, can  you keep trying to help me on this one? its still not working :(

  @IIIdefconIII 

Have you tried brand new configuration? Would be good to backup all settings. Then wipe out whole configuration from your device and set up VPN only? to see if then it will work.

If not or if you will have any issues, you always have the backup to roll back all settings at once.

Best Regards
