PPTP Broken?



  • Hi Guys, ..
    since using 1.3 Alpha i think PPTP is broken..
    PFSense Log:

    pfsense mpd: PPTP: Incoming control connection from XXXXX 57533 to XXXXX 1723
    pfsense mpd: pptp0: attached to connection with XXXXXX  57533
    pfsense mpd: No free PPTP link with requested parameters was found
    pfsense mpd: pptp0: peer's outgoing call request denied

    and my MacOSX PPTP Log:

    Thu Aug 21 12:30:36 2008 : PPTP connecting to server 'XXXXXX' (XXXXXXX)…
    Thu Aug 21 12:30:37 2008 : PPTP outgoing_call request failed, got result = 7, error = 0
    Thu Aug 21 12:30:49 2008 : PPTP connecting to server 'XXXXXX' (XXXXXXX)...
    Thu Aug 21 12:30:52 2008 : PPTP outgoing_call request failed, got result = 7, error = 0

    kind regards



  • I am also experiencing this problem on the latest build.

  • Can you both be more verbose about your setups and some tcpdump pcap file would be better too!



  • 800 error …



  • I am attempting to use pfSense as an independent VPN appliance.

    pcap file here:  http://idisk.mac.com/zevlag/Public/pptp1.pcap
    I'd recommend filtering to only see  192.168.15.74 and 192.168.15.192 it's running on vmware and picked up some random stuff.

    my WAN ip is:
    192.168.15.192
    I have no other interfaces.
    My firewall rules on WAN and PPTP VPN are:
    *  *  *  *  *  * none

    I've enabled PPTP server. I've created one user account.  If I can get this to work, I then want to enabled Radius Authentication.

  • Same problem on today's snapshot:

    Repeatedly in the logs:

    php: : Could not find gateway for interface(pptp).
    

    And then when I try to connect:

    Oct 1 20:29:54 	mpd: pptp0: killing connection with xx.xx.xx.xx 52656
    Oct 1 20:29:54 	mpd: pptp0: ctrl connection closed by peer
    Oct 1 20:29:54 	mpd: pptp0: peer's outgoing call request denied
    Oct 1 20:29:54 	mpd: No free PPTP link with requested parameters was found
    Oct 1 20:29:54 	mpd: pptp0: attached to connection with xx.xx.xx.xx 52656
    Oct 1 20:29:54 	mpd: PPTP: Incoming control connection from xx.xx.xx.xx 52656 to yy.yy.yy.yy 1723
    

    Where xx.xx.xx.xx is my IP and yy.yy.yy.yy is the pfsense public IP.

    I played with the new settings in the PPTP page but no combination seems to work. I am not using Radius so most of the changes don't affect my setup.



  • Just wanted to mention that I'm stuck with this problem too.

    I wonder if an install from scratch with the latest snapshot might fix it.



  • Sorry ENOTIME for now and still need to be convinced that i have the propper amount of troubleshooting data.



  • Was there a solution found to this problem?

    Or was this entry, "PPTP server - apparently had issues, now working. ", on http://devwiki.pfsense.org/KnownIssues121 the fix to this?



  • Try the latest build it actually should be solved with later snapshots.
