in USG FLEX H Series

Hello everyone,

I need your help, please.

I've got a big problem. I've set up an SSL VPN. I did everything as it should be. The configuration is fine, but when I try to connect from the client machine using the OpenVPN Connect client, I always get the same message: connection timeout.

So, I have no idea what to do next. I just spent so much time finding the solution.

Thank you in advance.

Greg

    Try using a DNS name in SSL VPN settings as the interface put the IP of the interface in config that might be wrong

    Does WAN1 have a WAN IP or is FLEX behind another NAT router?

    DNS name need to point to your WAN IP like a DDNS

    Hi @gregwl,

    Please kindly check you have allowed port 10443 on Secure-policy if the message is connection timeout.

    And did you have any logs regarding the attempted ?

    Thank you

    PeterUK,

    Yes WAN1 have WAN STATIC IP, no additional router, DNS is fine, pointing to my WAN IP.

    Hi Kevin,

    Which one exactly do you mean? Do I need to add an extra policy, or should I edit one of the existing secure policies? I tried allowing port 10443 on a secure policy, but I couldn't find the right one where I can allow port 10443.
