If your router does not support UPNP protocol well, VPN-Server cannot automatically generate VPN client configuration files. You will have to manually configure VPN client on smartphone/PC.
Here is the manual.

Alternatively, you may use the following configuration files as template. Simply replace the IP and username/password if applicable.
Blow are the sample configuration files that would have been generated by VPN-Server.
Right click on the link and click "Save Link as ...". Please replace 192.168.8.202 with your own router public IP.
Default username: test1
Default password: vpneveryone
We suggest that while you configure VPN client for the first time, you leave VPN server in default setting.
After you verify VPN client has been configured well, you can change default username & password on both VPN server and clients.
