Cobalt CacheRaQ 4 User Manual 67
Transparent Caching mode using one
network interface
Installation notes
• To avoid changes to the clients’ configuration, assign the existing gateway
address used by the clients to the CacheRaQ 4’s Network 1 interface.
• Assign a new IP address to the router/firewall.
• Use the new IP address of the router/firewall as the gateway setting on the
CacheRaQ 4.
Advantage
• The client machines do not require a special configuration.
Disadvantage
• If the CacheRaQ 4 fails, the clients cannot access the outside network until
the CacheRaQ 4 comes back online.
However, if the clients can be configured with multiple gateway addresses,
you can configure them with the new IP address for the router/firewall. The
clients can then use this address if the CacheRaQ 4 fails.
