Topic: PPTP Discarding Out of Order Packet

[Richard Loy]

Hi,

I tried to connect from an outside LAN to my office e-smith 4.1.2 server using a PPTP VPN tunnel.  (My server sits behind a CISCO PIX 515E firewall).

When the first workstation connects, everything works fine.  I could ping the server and other resources.  The second workstation could connect through the same public IP but cannot ping the server nor other network resources.  The first workstation also stopped working but not disconnected.  When I checked, I could see two PPP sessions (PPP0 and PPP1).  However when I checked the messages log file, I noticed some PPTP errors with lines of

Discarding Out Of Order Packet...

I disconnected the second the first PC and the second PC connection was also dropped.

I would like to understand the situation here.  Also, is there a way to overcome this problem?

Regards,

Doesn't help much but I can at least report that this issue is bugging me too. Never had any problems with PPTP but since I upgraded to 6.0.1 nothing but trouble.

If the 2nd connection is from the same source IP address (Happens if two workstations NATed behind a single router starts the PPTP to the same server) this will happen.
