Transparent 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’s Network 2 interface.
• Create a new subnet containing two hosts: the router
(assign it a new address) and the CacheRaQ’s
Network 1 interface. Make sure that the IP addresses
you assign to Network 1 and the router are on a
subnet different from the clients’ network. This is
necessary for the CacheRaQ to pass traffic through
from the clients to the router.
Advantages
• No special configuration for the client machines is
necessary.
• All traffic is forced through the CacheRaQ, so precise
logs and statistics can be generated.
Disadvantage
If the CacheRaQ fails, the clients cannot access the
outside network until the CacheRaQ comes back on-line.
