The 2310n supports only two VPN tunnels. But they can be any combination of "dial-in" (client to router) or site-to-site (router to router) connections using PPTP, IPsec or L2TP/IPsec protocols.
Draytek provides its Smart VPN client free for download, which I tried unsuccessfully to use on an XP SP3 notebook to open an IPsec tunnel to the 2130n. This was a few months ago, however, and Draytek has since released a newer version of the utility (220.127.116.11) that I didn't try.
But in the meantime, I took at shot at trying to connect using the VPN Wizard built into Win 7's Network and Sharing Center. I configured the 2130n as shown in Figure 7 and set up a user with only IPsec/L2TP enabled.
Figure 7: VPN IPsec client tunnel setup
On the Win 7 client, I just did the following:
- Opened the Network and Sharing Center
- Chose Set up a new connection or network, then Connect to a workplace
- Chose No, create a new connection, then Use my Internet connection (VPN)
- Entered the WAN IP of the 2130n
- Entered the username and password of the test user I set up
- Clicked the Connect button
Because I disabled the fallback of a PPTP connection, this didn't get me connected. So when the connection failed, I then chose Set up the Connection anyway to save it so that I could make the required changes. After going back to the Network and Sharing Center, I just opened the saved connection and made the settings shown in Figure 8 in the connection Properties. I also clicked the Advanced settings button, to enter the preshared key I'd set in the 2130n.

Once the changes were made, the connection opened within seconds of clicking the Connect button. The 2130n's Remote Dial-in Status screen (Figure 9) showed the successfully opened tunnel.

I should note that the VPN setup information in the system log was detailed and informative, something not always found in VPN endpoint routers.
I used LAN Speed Test to run a quick check on the 3DES encrypted IPsec tunnel, using a 10 MB file size. Figure 10 shows 1.15 Mbps client to router and 1.3 Mbps router to client.
