[vpn-help] Issues connecting to company VPN using mobile broadband

[Guido 嵬 到]

Hi,

Just to let you know, I solved this issue by changing the "Connection
Type" parameter in my mobile broadband connection software.
The VPN did not work with the default "NDIS" connection type, I had to
set it to "RAS(modem)".
