Title: DFL-800 PPTP server only works with the first client
Post by: robertop on October 05, 2015, 07:50:43 AM

Hi all!
I have configured the PPTP server in the DFL-800 according to the manuals.
It works perfectly whith the firs client connected. The problem its for the next clients (from another public IP).
The second one connects without problem, the tunnel established correctly, but there is not connectivity.
I tried to ping from second client to a internal server inside the local net behind DFL-800, but no answer.
I show the packets incomming in the internal server whith wireshark (ping request), and I can show the answers also (ping reply).
But the answers dont reach the client. It seems that its lost in the DFL-800.
The ping reply have dst ip = 10.0.10.242 and my pptp-pool is 10.0.10.[241-249]. All looks good!.

My DFL-800 have firmware version 2.27.03.25-14780.

Somebody have a similar problem?
Any Idea?

Thanks!

More info:
I can connect from two diferents clients from two publics IPs simultaneously to the DFL-800.
The first one pings perfectly devices behind DFL-800.
The second one cant ping devices behind DFL-800.
I disconnect the first client.
Immediately the second one pings perfectly devices behind DFL-800.

If no body responds, you may want to phone contact your regional D-Link support office and get help on this.

There is someone who has achieved several incoming PPTP simultaneous connections with success?

Looks like your DFL-800 sits behind a NAT router which is configured for PPTP passthrough but only supports one PPTP tunnel at a time?

EDIT: ... or both clients reside behind the same NAT router that has this restriction.
