Hi everybody! I have an issue, even if it's not a problem to connect with remote access (in the picture bellow), but i want to fix it. Where or how I can create and define certificate to remote access clients?

Updating Media

Thanks!

You would always see such a warning presented when connecting very first time to the gateway. AFAIK, dont believe there is a way to circumvent that. It only comes up once, never again.

Either way, looking at your attachment again, it makes me wonder if cert presented by the gateway is okay. Can you verify the cert is valid on gateway object?

yes ) the customer have only 5 concurrent conections, and use it only for RDP, for him it's difficult to instruct every employee for how install/update and do other things. So this option of connecting through a browser is more convenient and practical for him

You need a certificate that is trusted by the clients, and then install for the VPN portal.

The internal certificate will always give a warning if it is not already trusted by the clients.
