My favorite technique is to ifconfig eth0:0 or whatever to a virtual
number, with the -arp flag.
This works great on 2.0.36, not sure about the 2.2.x kernels.
We have successfully used 2.0.36-vs (direct routing method), but
it does fail at extremely high loads. Seems like a cumulative effect,
after about a billion or so packets forwarded. Some kind of kernel memory
leak, I'd guess.
