Note: All of the pages in this section are available in all three operating modes—stand-alone Web
Appliance, joined Web Appliance, and Management Appliance—however, not all features on the
Network Interface and Hostname pages are available in every operating mode. See the
documentation for those pages for detailed information about what features are available in each
operating mode.
■
Use the Network Interface page to configure your appliance’s IP address and its access to
DNS servers.
■
Use the Hostname page to set your appliance’s hostname as well as an upstream or
downstream proxy.
■
Use the WCCP page to enable
Web Cache Communication Protocol
(WCCP) integration
between your Web Appliance and WCCP-enabled routers.
■
Use the Network Connectivity page to test your appliance’s connection to any upstream
proxy, your ISA/TMG server, the internet, and to Sophos.
■
Use the Diagnostic Tools page to troubleshoot connection problems between the appliance
and other servers on the internet.
4.5.1 Configuring the Network Interface
Neither the Deployment Mode option nor the Configure button are available on the Management
Appliance, as deployment modes are not relevant.
Use the Configuration > Network > Network Interface page to configure your appliance’s IP
address and to configure access to your network’s DNS servers.
Note: The appliance uses 172.24.24.173 as the network address to access its initial configuration.
This may cause routing conflicts if your local network also uses addresses in the range of
172.24.24.0-255. Contact Sophos Technical Support for a solution if this applies to your
deployment.
Important: If WCCP is enabled (on the Configuration > Network > WCCP page), all network
settings on the Network Interface page, except Specify the DNS servers, will be disabled until
you turn off
Web Cache Communication Protocol
integration.
1. Select either DHCP or Static IP.
If you choose the DHCP option, the Obtain DNS servers automatically option button is
selected by default. DHCP is not recommended for a production environment, as the IP address
can unexpectedly change, disrupting your users.
If you choose the Static IP option, you must also fill in the following text boxes:
■
Enter the IP Address for the appliance.
■
Enter the Network Mask. The
is the range of addresses that the appliance
can connect to directly. IP addresses outside of this range are reached via the Default
Gateway.
■
Enter the IP address of your network’s Default Gateway.
