    PPTP not connecting - Error 619

      Hello All,

       

      Here's one that has me stumped.  I have 3 home users with Linksys WRT400N Wireless routers.  At our side, we have an SG560.  The users are able to establish a PPTP session with the SG560 if they are not behind the WRT400N.  As soon as I put the PC behind the WRT400N router, the connection does not establish.  The user attempts to connect, the initial connection is established, the connection tries to verify the username and password, then after a minute or so, fails with Error 619.  Details:

       

      1. SG560 with 3.2.2 firmware

      2. Home users have a mix of DSL (PPPoE) and Cable ISPs

      3. DSL connection is set to establish the PPPoE connection from the router, not the modem.  Cable connection to not require authentication

      4. All WRT400N routers are enabled with VPN Pass through, specifically PPTP Pass Through

      5. I have opened the necessary ports back to the users home computers

      6. WRT400N is on the latest firmware available

      7. I have put the PC in the DMZ of the WRT400N, but no luck

      8. We are using the built in PPTP client in Windows XP (SP3)

      9. Linksys support has not been able to resolve the issue, and have given me a 48 hour turnaround time (which of course I can't wait for)

       

      Has anyone else experienced problems connecting using PPTP when behind Linksys routers (or even this router if you have it)?  I've googled this to my wits end and have tried everything I can think of and suggested.  Here is what I am seeing in the SG log:
