We have a development client website which we can access from office network as you office public address is added to an exception. However, when we have our employee visiting client meeting at client site using their guest wifi they cannot access the website for reference though client access and show the website as they are connected to authorized network not guest wifi.
If is difficult to create IP exception, even, if they are using office VPN their source IP is still client guest network and whatever public IP they have for guest network from ISP for guest network. We cannot ask them to create exception to their guest IP, if it is not assigned static IP or ask them for vpn just for meeting.
One solution I could think is to create remote desktop for out team visiting client. So they could remote in to our remote desktop using VPN and they access the website using the desktop that is in our physical LAN.
Is there any other solution that is more effective for such situation where we cannot request for direction access to client VPN, external trust or change their guest network apart from IP exception, which will probably change in guest network.
