The PPTP and IPsec capabilities are not a strong point of the ASAP / BOSS duo. Figure 7 shows the simple setup screen for the PPTP server, which users experienced with PPTP setup should be able to figure out.

Since I'm not in that category, however, I needed more help, which I didn't find in either User manual. Fortunately, ioGEAR has a Support Note that, though flawed, gave me the clues that I needed to get my WinXP client successfully connected via a PPTP tunnel.
Once you set up the PPTP server, you'll also need to make a visit to the Users page (more later) to set up an account for each user who'll be using the PPTP server. Once you do connect, note that since NetBIOS broadcast isn't supported, you'll need to find your way around the remote network by using the IP address of the computers that you wish to connect to.
I hope purchasers looking to use more secure IPsec VPN capabilities of the ASAP / BOSS have more luck than I did. Figure 8 shows the very limited IPsec configuration options, which provide no indication of either encryption or authentication options.

The manual was useless, and requests to both Tritton and ioGEAR for a detailed IPsec setup example were fruitless (I did learn that Perfect Forward Secrecy isn't supported, however). And if you decide to try to figure it out yourself, the IPsec client you use better give you any debugging information you need since tunnel setup logging isn't available for either PPTP or IPsec!
If you need to connect to a remote VPN gateway through the router, PPTP and IPsec pass through are supported, but not L2TP. Both companies say there is no hard limit on the number of pass through sessions, and that they can connect to multiple remote gateways. Forget planning on setting up your own PPTP or IPsec gateways behind the product, however, since the Virtual Server feature won't support the protocols required for either VPN method.
