Hello,
I am trying to connect to a an AWS server that is on eu-west-1.rds.amazonaws.com. I am using AWS VPS Client to do that. Before switching to Sunrise from UPC, I was able to do it without any problems. Also, when I switch to my mobile phone network and connect, it works. I checked it by inputting a nslookup calling the server in CMD. It gets a timeout on Sunrise network.

However, when I am on Sunrise network. The AWS server is not recognized, it like the VPN no longer works. I tried switching to public DNS like the Google one. It doesn’t work. Also, as far as I see I do not have any Surf Protect product enabled in My Sunrise.

Could you please help me address this problem?

      elzbieta I have enabled the UPnP protocol on your modem, which now opens the ports automatically. Please test it again. Alternatively I recommend to open the VPN ports. You can find instructions here (in german).

      Does it work with active UPnP service?

        Thank you. However, it does not work with the UPnP. I cannot open the VPN ports as I do not have the right permissions to do so. It is a different team at my company that manages the AWS VPN. Is there are different way still to address this problem?

        Have you tried to factory reset your modem? >25s with a needle into the hole on the back of your modem. This while the modem is running. You loose your individual settings.

        Maybe something hangs since the switch from UPC to Sunrise.

          Sounds like your trying to connect to AWS Client VPN to access your AWS VPC, and have a DNS issue, Title is abit misleading, AWS use OpenVPN, so you basically get the service open on UDP port 1194, and yes that works over the Mobile CGNAT network,

          however you’ve possible UDP blocked, try bring up the connect using a different client or over the OpenVPN CLI, as you can download the configuration

          Connect using an OpenVPN client application - AWS Client VPN (amazon.com)

          also check if you have issue connecting to the VPN, and compare your public IP e.g https://ifconfig.co/, if you get a sunrise or amazon one,
          resolve the VPC IP of the RDS endpoint before connecting the VPN, and see if you can access it. e.g 10.x.x.x or 172..x.x.x etc..

          But this doesn’t look like a specific sunrise issue, as I use AWS Client VPN daily also on Sunrise network

          Thank you for all the suggestions. I tried them, but what worked in the end is our backend team added the internal DNS address to the VPN config. Basically, the “Enable DNS servers” toggle was inactive before.
