I'm not sure if you're trying to do something similar to what I'm
attempting, but I'm guessing you are (else why MASQ an alias?)
Basically I want to MASQ a subset of computers through a different IP
address. I want to use aliases because they are all routing through
the same subnet, and I'd like the solution to be scalable beyond
n-1, where n is the # of PCI slots free, or in my case n-2, since
there is a third network involved.
So far, using IPchains and IPmasqadm, there have been no problems,
but I also need iproute2 to work with aliases, and that might be a
snag. In short, the plan is to use source based routing to route the
subset to the desired aliased port. If anyone has any experience
with the package or doing something similar I'd like to hear.
