I have a simple problem that is becoming impossible for me to figure out on my own. 

Here is my issue. 

I have 5 static IP address and I use one of them for my VPN connection.

My R600VPN router I am using as my VPN connection is on my Static IP WAN of xxx.xxx.52.29

What we want to do is have the WAN xxx.xxx.52.29 connect to the R600VPN and have port 5 on the router plug into our 24 port switch so that the users will be able to join the lan as if they were plugged directally on the lan.

We can connect to the VPN router using L2tp over IPsec and I can see my art guy Ryan on the router with me when I scan the connection but we are not able to see any of the connected computers. We need to be able to see the connected computers so that we can send artfiles to our IP Printers and connect to our NAS drives. 

My Lan has a subnet of 192.168.87.0 (router is 192.168.87.1) connected to a google WIFI that runs DHCP for the network. The IP range for the Google Wifi is 192.168.87.20-250

The R600VPN is on the subnet 192.168.0.0  (router is 192.168.0.1)

Again we don't have an issue connecting to the R600VPN it's just the passing through Port 5 onto the lan with the IP address that works on the .87 network. 

PLEASE HELP! and thank you
