• Type ipconfig /all or ipconfig -all to view the network configuration.

For advanced user only

Instead of the default gateway you can build your route manually. This is helpful if you use instant messaging clients and/or filesharing clients simultanously with the vpn connection. Therefore deselect the option Use default gateway on remote network . Open the command shell (run - cmd - enter) and type the following three lines sequently:
route -p add 87.77.0.0 mask 255.255.0.0 130.133.52.242 metric 5
route -p add 130.133.0.0 mask 255.255.0.0 130.133.52.242 metric 5
route -p add 160.45.0.0 mask 255.255.0.0 130.133.52.242 metric 5

Important!

It is possible that an "Access denied" error occurs during login after configuring the VPN Connection. To solve that problem follow these steps:

• Check the properties of the VPN-Connection (see instruction above).
  

• Next step is to search after the following filetype *.pbk .
  

• Open the file with notepad ( right-klick --> Open with…)
  

• Search for "UseRasCredentials=1" and replace with the following: UseRasCredentials=0
  

• Save and exit.
