Hi, i buy a few years ago the vr600v2 to use it with the adsl of movistar,now that the adsl its closing and we move to the optic fiber, i want used it as second router, but i have varius problems doing   it.

Now,The 1st router was the hgu (192.168.1.1), that was conected to transparent switch  And the tplink was connected to the switch.

1.Two seperate lan: hgu=192.168.1.1 and tp link 192.168.1.3 static ip(router mode) with lan in 192.198.113.1 and openvpn server in 10.8.0.5(default).

The problem was the devices in hgu lan can't wiew the samba server of tp-link, i have try open ports  of samba in the tp-link but he don't appear do it. I can ping to devices from hgu lan to tplink lan and vpn lan.

I have try add two static routers to the hgu one for tplink lan and and anohter for the vpn lan to 192.168.1.3

Using the vpn, the sharing usb its not detected,only works if i write  the server ip(192.168.113.1) directly in videolan in my android mobile, but ftp works perfect.

In the other hand if i try put the two routers in the same lan, all can view  the samba server of the tplink,but i can't use openvpn server, because the router always things is unconneted to internet in the status page(but all devices have internet over lan), so it fails to connect with no-ip dynamic dns.
