Its a long shot, but has anyone had any success using DD-WRT's built-in VPN client to connect to the TL-R600VPN PPTP server. My DD-WRT router seems to make the initial connection, but then promptly disconnect. The logs from the TL-R600VPN are as follows:
[CODE]Index Time Type Level Log Content
51 Mar 17 23:37:15 VPN INFO PPTPS CTRL: Client pppd finish wait
50 Mar 17 23:37:15 VPN INFO PPTPS CTRL: Client pppd TERM sending
49 Mar 17 23:37:15 VPN INFO PPTPS CTRL: Client XXX.XXX.33.72 control connection finished
48 Mar 17 23:37:07 VPN INFO PPTPS CTRL: Starting call (launching pppd, opening GRE)
47 Mar 17 23:37:06 VPN INFO PPTPS CTRL: Client XXX.XXX.33.72 control connection started[/CODE]

I've used the connection settings as suggested on the DD-WRT wiki, but perhaps there is a specific adjustment I need to make in order to maintain the connection?
