If this is not possible, the default gateway of your computer probably cannot be accessed.
In this case, your computer should be simulated as follows:
Initializing the default gateway
Determine the currently valid default gateway address.
•
Under Windows XP, carry out the steps described under "Configuring the network in-
terface" on page 170 to open the "Internet Protocol (TCP/IP) Properties" dialog box.
•
If no IP address has been specified for the default gateway in this dialog box (e.g., be-
cause "Obtain an IP address automatically" has been activated), then enter the IP ad-
dress manually.
To do so, first select "Use the following IP address", then enter the following addresses,
for example:
IP address:
Subnet mask:
Default gateway:
•
In DOS (Start, Programs, Accessories, Command Prompt), enter the following:
arp -s <IP address of the default gateway> 00-aa-aa-aa-aa-aa
Example:
You have determined or specified the address of the default gateway as: 192.168.1.1.
The command should then be:
arp -s 192.168.1.1 00-aa-aa-aa-aa-aa
•
To proceed with the configuration, establish the configuration connection (see "Estab-
lishing a local configuration connection" on page 172).
•
After configuration, reset the default gateway. To do this, either restart the configuration
computer or enter the following command in DOS:
arp -d
Depending on the configuration of the mGuard, it may then be necessary to adapt the net-
work interface of the locally connected computer or network accordingly.
192.168.1.2
Do not under any circumstances assign
an address such as 1.1.1.2 to the config-
255.255.255.0
uration computer.
