I have a small office with four Win10 desktop computers linked to a TP-Link Archer C9 v3 wireless router. I need all four of them to connect to a remote network via vpn, and I’ve figured out that I can connect any of them individually, but not all of them at the same time. As a result, if I connect computer #1, computers #2, 3, and 4 will not connect. However, if I connect #2, it works, but #1, 3, and 4 are unable to connect. I don’t believe the problem is with the remote network because there are a few other users who are linked remotely; however, none of them have more than one device connected via VPN at their location. They’re using the built-in VPN client in Windows 10 with L2TP w/PSK.
The router, according to TP-Link, supports VPN passthrough. When I logged into the router, I went to Advanced> NAT Forwarding > ALG, and everything is checked, but the boxes for the following are explicitly checked: Is there anything I can do to link all four computers to the VPN at the same time?
OpenVPN is a free VPN (virtual private network) service that lets you connect to your home network from anywhere you have access to the internet. OpenVPN is a multiplatform service that operates with both Android and iOS operating systems to give you access to your router’s devices and services.
Note: The content you can view over the VPN is determined by the Client Access option you choose. Internet and Home Network would allow you to access your network shares as well as use your home internet service. Home Network Just gives you access to your network’s shared files and drives but not to your home internet service.

TP-Link offers a wide range of VPN routers for both residential and business users. The most popular TP-Link routers, such as the SafeStream VPN routers for companies and the popular Archer WiFi routers, are completely compliant with VPN Tracker 365.
Please see the table below to see if VPN Tracker has been successfully checked with your TP-Link router by the VPN Tracker team. You’ll find configuration guides for your TP-Link system here if they’re available. You’ll be able to set up remote access to your TP-Link interface and internal network on your Mac using these setup guides.
Until today, this setup worked flawlessly. It became unstable all of a sudden: whenever I tried to move something 5+M, it became unstable. The VPN, of course, fails. The notebook will still communicate with the router after that, but not after that (i.e. the WAN). The router can be rebooted as a solution.
The problem seems to have begun with the router’s (as a client) first DHCP renewal with the ISP (as the server), however neither the cable modem nor the router rebooted fixed the problem.
When I migrate the same files without using the Cisco VPN, the issue does not appear to exist. It happened before on another Windows 7 laptop, but without a Cisco VPN, and it wasn’t as persistent (perhaps one reboot per week).
I’m guessing it’s because of a conflict between the router and Cisco VPN, or maybe the router and Windows 7, but how do I figure out who’s to blame? What’s the answer until I find out what’s causing the problem?
EDIT: When this happens, the notebook can access the router’s admin GUI, but other functions such as DHCP renewal and DNS lookup fail. The router receives “DHCP INFORM” but does not submit “DHCP ACK,” according to the router logs. The router, according to Wireshark, does submit “DHCP ACK.”
