• Check your TCP/IP configuration according to Installing and Setting up
the Safe@Office Appliance on page 17.
• Restart your Safe@Office appliance and your broadband modem by
disconnecting the power and reconnecting after 5 seconds.
• If your Web browser is configured to use an HTTP proxy to access the
Internet, add "my.firewall" or "my.vpn" to your proxy exceptions list.
My network seems extremely slow. What should I do?
• The Ethernet cables may be faulty. For proper operation, the Safe@Office
appliance requires STP CAT5 (Shielded Twisted Pair Category 5) Ethernet
cables. Make sure that this specification is printed on your cables.
• Your Ethernet card may be faulty or incorrectly configured. Try replacing
your Ethernet card.
• There may be an IP address conflict in your network. Check that the
TCP/IP settings of all your computers are configured to obtain an IP
address automatically.
I changed the network settings to incorrect values and am unable to correct my error. What
should I do?
Reset the network to its default settings using the button on the back of the
Safe@Office appliance unit. See Resetting the Safe@Office Appliance to Defaults
on page 422.
I am using the Safe@Office appliance behind another NAT device, and I am having problems
with some applications. What should I do?
By default, the Safe@Office appliance performs Network Address Translation
(NAT). It is possible to use the Safe@Office appliance behind another device that
performs NAT, such as a DSL router or Wireless router, but the device will block
all incoming connections from reaching your Safe@Office appliance.
To fix this problem, do ONE of the following. (The solutions are listed in order of
preference.)
