I use the Draytek 130 as well and can connect to it perfectly fine. The 130 is actually a full router with the routing capabilities disabled in software, but it has a perfectly good web interface and telnet as well.
The way I have it configured in my router (pfSense) is that the PPPoE connection and WAN connections manifested as two separate interfaces. While the PPPoE connection is the main 'WAN', it is actually just a tunnel to the ISP. The underlying WAN interface can be configured with separate address space. While the Draytek will give you a DHCP address, it's better to restrict it to just the /29 you need, and have the WAN on 192.168.2.2.
As the modem is on the wrong side of the firewall, you shouldn't need to change any firewall rules, and the router will route from your LAN to your modem (make sure your LAN is using a different address space, obviously!). Then from your PC, just visit http://192.168.2.1 as you need (web interface is very high level on info, but you will need to go there mainly to update firmware). Better information is available via telnet (use PuTTY, in Telnet mode), and login to the prompt. All stats are available by typing 'vdsl status' (for Interleave/FastPath and sync status) and 'vdsl status more' (for FECs etc). Default user/password is admin/admin
Here's mine for example:
