I have PC2 connected to a VPN (L2TP/IPsec) server I have setup on R2. I need PC2 to be able to ping PC3 and PC4, but it's not working. When I use a Windows machine to connect to the VPN I can ping hosts under R2, but that is not the case with my Linux machine (Raspbian Jessie). I believe the solution has to do with the routing table but I have no idea what I am doing there.I know that I am connected to R2 from PC2 because when I type 192.168.1.1 into the browser I am greeted with the remote router's login screen.PC2 is 192.168.1.125 under R1, and it is 192.168.1.69 under R2.The public IP for R2 is 76.73.240.120. Here is the current routing information:root@raspberrypi:/home/pi# ip route showdefault dev ppp0  scope linkdefault via 192.168.1.1 dev wlan0  metric 30376.73.240.120 via 192.168.1.1 dev wlan0192.168.1.0/24 dev wlan0  proto kernel  scope link  src 192.168.1.125  metric 303192.168.1.1 dev ppp0  proto kernel  scope link  src 192.168.1.69What do I need to do in order to get PC2 to be able to ping the hosts under R2?
