Hi hopefully someone can help. I've set up a Qnap NAS with PPP VPN, mapped shares in the office on the local network with 192.168 etc but to use those drives remotely with the VPN they have to be mapped to 10.0.0 etc. What is the best way to handle this - create two mapped drives one for local one for remote and named accordingly? Or is there any way to have the same IP address in both locations?

I think I know what you mean.

The VPN server hands out addresses in the 10.x.x.x subnet, for clients, but the remote lan is 192.168.x.x.

I have always found that you can access the 192.168.x.x lan when connected to the VPN.

How are you trying to connect to the samba share? )Maybe just try mapping from command line using IP's)

Remember that you may not get all broadcast traffic for network browsing on some VPN's. I cant remember what traffic a PPP VPN will transmit.

What kind of VPN server are you using (or does the QNAP provide it?). You would probably be best to go with OpenVPN as it can pass routes to the VPN client e.g. is your main subnet with QNAP device is your VPN subnet

You can tell OpenVPN to advertise

Maybe look at IPv6? No VPN necessary then :)

I would run a batch script something like this

net use z: /d
net use y: /d
net use x: /d
net use z: \\192.168.0.x\sharename
net use y: \\192.168.0.x\sharename2
net use x: \\192.168.0.x\sharename3
net use z: \\10.0.0.x\sharename
net use y: \\10.0.0.x\sharename2
net use x: \\10.0.0.x\sharename3

Then just double click on the batch file after you connect the ppp session or are connected locally to the same network as the qnap.

When the batch script runs, it does three things
1) Deletes the mapped drives X,Y,Z
2) Tries to connect X,Y,Z to the qnap when in the 192 range. If it cannot connect, they fail and it moves on
3) Tries to connect X,Y,Z to the qnap when in the 10 range. If it cannot connect, it probably already has when you are in the 192 range, or it will fail and move on to closing the script.

if you need to connect to the qnap with a specific username and password, use the command
net use z: \\192.168.0.x\sharename /user:Username Password
with a simple space between the username and password.
If you get errors saying that you cannot connect twice with the same username, for drives x and y you would connect without the usename and password because you already logged on when you mapped the z drive.

edit: the script will run so fast you cannot see the errors - so to troubleshoot, replace the exit command with pause and it will stop before closing the window at the end.
