Title: DFL-210, PPTP VPN Clients, one telnet at a time???
Post by: mjchabby on July 26, 2010, 06:42:44 AM

Hello, I have my DFL-210 setup and running fine with a PPTP server used for salesman to telnet into our UNIX system and place orders.  Our problem now is that only a single user can login to the UNIX server at a time.  Three or more can login to the PPTP vpn simultaneously, however only the first person attempting to login to the UNIX system can.  The remainder of the connections hangup at the SYNACK_S stage. 

Any suggestions?

Marc

Can you access your UNIX server from LAN (without DFL usage) mote that one time at the same time?

Show your IP rules.

Yes, we can do that no problem.  Here are the relevant rules:

Action: Allow
From: PPTP_Server, all-nets
To: lan, all-nets
all-services

Action: NAT
From: PPTP_Server, VPN-Clients
To: DSL, all-nets
all-services

Hi all,
I'm experiencing the same trouble with RDP access.

I think I fixed the problem, remove anything from the "Networks behind user" section in the user database.  I had two people connected at once this morning.

It worked too for me :)
Thanks
