I have an ISP provided modem/router - Router1
I have another router (which I cannot install DD-WRT on) - Router2
Router2's WAN port is connected to a LAN port on Router1 and I use Router2 to connect to a VPN using a PPTP setup. All devices connected to Router2's wifi will get internet access through the VPN. All devices connected to Router1 will get normal internet access.
The problem is that I cannot access samba shares of devices on Router2 from devices on Router1. Is there a way to achieve this?
