Hi,

of course, i think there are several user who can read and i think write in english.

Please connect via Telnet/SSH to the LANCOM and perform a "trace # vpn-st", also exectue "show vpn long" and check if the defined Networks are correct.
Also check if the correct VPN Rules are defined in the LANCOM Configuration under "Configure: FirewallQoS/Rules/Rules".
In the Advanced VPN Client please also check if the Networks are set up right.

Hi,

i am sorry, but i do not have any experiences with the UMTS Card directly attached to the Laptop.
Did you "play" with the settings in the AVC? For example "use Microsoft DUN Dialer".

Hi

What kind of VPN connection did you configure?

You must be aware that you when using a UMTS connection you are NATted by the mobile phone provider. Moreover, some providers require a special tariff and the use of a different APN to use VPN connections.

Hey,

I have the same problem:
with AVC and "normal" Internet everything is ok, with AVC and UMTS (E-Plus, private Address, Range 10.x.x.x) it dosn't work. The connection is established, but it is not possible to transfer Data.

But, i hav the same problem, when I use pptp without the AVC and with a W2K-Workstation as dialin-server. With "normal" Internet it works, with UMTS connection is established, but it is not possible to transfer Data.

So, I think it is because the NAT.

I thougt that the special APN's (like: ipsec.eplus.de) are only important for using with IP-Sec, not for PPTP but it seems this is not correct.

Update:
I talk with the E-Plus Hotline, they told me, that the VPN must work with my Contract, they wold ask a Technikan to Call me Back within the next 48 Hours to resolve the Problem......

Update 2:
With Vodafone it works

@future.....
I made the Connection with the Vodafone-Software (Internet works) then I use my AVC-Profile, that I also use for the "normal" Internet, press "Connect" and it worked with vodafone-germany.
