Help with VPN (DSL/PPoE)

[mhaddyrsm]

Here is my network:

Speedstream 4200 Modem (DSL over PPoE) -> Cisco RV220w

I have created a QuickVPN client on the RV220w but when I use the public facing IP address and try to connect using these credentials, I just get a 'remote host cannot be reached' type of error. Is anyone familiar with the Speedstream 4200 modem? Do I need to change it to BRIDGE mode or change something so that it'll work with the RV220?

The modem is now in BRIDGE mode so the RV220w now has the public IP. I've followed the router admin guide to add a QuickVPN client and used the QuickVPN client software on an XP machine outside of the network to try and connect. I get the usual "failed to establish a connection" error message. And yes, I've disabled the Windows firewall on this machine.

I really need someone to hand hold me to get this set up, or at least point me to some pretty detailed walkthroughs online.

Can anyone help?
