68 Cobalt CacheRaQ 4 User Manual
Transparent Caching mode using two
network interfaces
Installation notes
• To avoid changes to the clients’ configuration, assign the existing gateway
address used by the clients to the CacheRaQ 4’s Network 2 interface.
• Create a new subnet containing two hosts: the router (assign it a new
IP address) and the CacheRaQ 4’s Network 1 interface. Ensure that the
IP addresses you assign to the router and to Network 1 are on a subnet
different from the clients’ network. This is necessary for the CacheRaQ 4 to
pass traffic through from the clients to the router.
Advantages
• The client machines do not require a special configuration.
• All traffic is forced through the CacheRaQ 4, so precise logs and statistics
can be generated.
Disadvantage
• If the CacheRaQ 4 fails, the clients cannot access the outside network until
the CacheRaQ 4 comes back online.
