Deleting Temporary Files
Browsers store local copies of web pages as temporary files. If you upgrade to a
new GUI resource file, or if you encounter problems in browsing to the GUI,
you may need to delete these files (clear the cache). To clear the cache in
Internet Explorer:
1. From the Tools menu, select Internet Options.
2. On the General tab, click the Delete Files button.
3. The Delete Files dialog box opens. Click the OK button.
To clear the cache in Netscape 6.2.x:
1. From the Edit menu, select Preferences
2. Click on the Advanced menu option to expand it.
3. Select the Cache menu option
4. Click the Clear Memory Cache and Clear Disk Cache buttons.
Accessing the Router via the GUI
Problem You cannot browse to the router.
Diagnosis Check if you can ping the router’s interface from your PC. If you get a
response, this indicates that the interface’s IP address is valid, and that your PC
has a route to it. Note that you will not get a response if Respond to ping is
unchecked on the Firewall Policy Options page (Configuration > Firewall >
Interfaces > Policy options). This option is checked by default.
Solution ■ If you cannot ping the router’s interface:
• Check that your PC’s gateway is correct, so that your PC has a route to
the router.
• The IP address of the router’s interface may be incorrect. To correct this,
access the CLI and use the IPADDRESS parameter of command SET IP
INTERFACE
• The IP address of the router’s default gateway may be incorrect, so that
the router does not have a route back to your PC’s gateway. To correct
this, access the CLI and use the NEXTHOP parameter of the command
ADD IP ROUTE or SET IP ROUTE.
■ If the router should be dynamically assigned an IP address, check that the
DHCP server can reach the router, by pinging the router from the DHCP
server. Note that you will not get a response if Respond to ping is
unchecked on the Firewall Policy Options page (Configuration > Firewall >
Interfaces > Policy options tab). This option is checked by default.
■ If your PC accesses the Internet through a proxy server, you may need to
set your browser to bypass the proxy when browsing to the router’s IP
address range. See “HTTP Proxy Servers” on page 25 for more
information.
■ If you cannot access the GUI because your username or password fails,
check that you are spelling them correctly. The username “manager” will
always be valid. Its default password is “friend”. Note that passwords are
case sensitive.
