kernel: netfilter: add IPVS kernel module support
IPVS (IP Virtual Server) implements transport-layer load balancing inside the Linux kernel, so called Layer-4 switching. IPVS running on a host acts as a load balancer at the front of a cluster of real servers, it can direct requests for TCP/UDP based services to the real servers, and makes services of the real servers to appear as a virtual service on a single IP address. This change adds the following kmod packages - kmod-nf-ipvs - kmod-nf-ipvs-ftp - kmod-nf-ipvs-sip Signed-off-by: Mauro Mozzarelli <mauro@ezplanet.org> Signed-off-by: Florian Eckert <fe@dev.tdt.de>

In the virtual server via Network Address Translation,

|
the IP address and port number of real servers cannot be sent to
|
||||||
|
clients in ftp connections directly, so FTP protocol helper is
|
||||||

required for tracking the connection and mangling it back to that of
|

virtual service.
