My son has a Samsung Tab A tablet with Cell-Data/WiFi. My end goal is that when my son has his tablet away from the house, his tablet connects to my home CR109 via an L2TP/IPSec VPN (I am doing this because we have some specific filters set up for him and I want to keep them active at all times). I have the Samsung tablet set to have the VPN "always on".
I have the VPN setup and it works perfect when he is not on our home wifi network. But when he connects to the network in the house, the VPN connection fails, and he cannot access the internet.
I am not sure what configuration settings you may need to see, but I will provide any information needed to help with this.
My network setup is 192.168.15.xxx. When the tablet connects inside the network, the DCHP server sets the IP address to 192.168.15.62. When the tablet connects via the VPN, the remote address is set to 192.168.15.29.
What am I doing wrong? Thank you in advance for your help!
