blems in the case of the assignment of a private IP address to the
LANCOM UMTS Router.
If no VPN connection can be established when using the main mode,
adjust the method in the VPN connection list to "aggressive mode" in the
appropriate profiles at both ends.
To do this in LANconfig, go to the ‘VPN’ configuration area on the ‘Gene-
ral’ tab and select the relevant connection from the ‘Connection list’. First
set the dynamic VPN option to 'No dynamic VPN'
and then activate
'Aggressive Mode'
as the IKE exchange mode.
In LANconfig, you then enter unique identities (e.g. unambiguous e-mail
addresses) for the relevant connection in the configuration area ‘VPN’, tab
‘IKE parameters’, in the list for ‘IKE key’.
The settings for the aggressive mode must agree for all of the identi-
ties at both ends of the connection!
The provider assigns a dynamic IP address to the UMTS/HSxPA card when
it logs in to the mobile telephone network. Be aware of the corresponding
settings when carrying out the configuration with the Setup Wizard.
