Here is a patch to the RedHat Pulse/Piranha system that let's you use
NAT port rewriting:
http://mobiuscircle.com/2009/06/08/piranhapulse-patch-allow-port-rewriting-in-nat-mode/
This patch adds the ability for you to set a port in the real server
config section in /etc/sysconfig/ha/lvs.conf
eg:
...
virtual http-shared {
port = 80
...
server rack104 {
address = 192.168.2.104
port = 8080 <==== Isn't normally supported by pulse/piranha
active = 1
weight = 1
}
...
}
...
Best,
James
