I was using DD-WRT V23 but could not get an L2TP connection to work. I then plugged my PC directly into my cable modem and it worked fine. I thought maybe it was DD-WRT so I flashed Thibor 12 but I still have the same problem. Does anyone have this working or any advice on getting it fixed? FYI: The VPN server is connected to a real IP, not behind a NAT'ed box and my internal network is on a different set of IP's then the VPN's internal network.
