Good, this will solve the problem with individual cameras. But it
doesn't solve the multicast problem. Anyhow, I might survive for now
without actually sending multicasts if I can receive them, which leaves
me with two options:

1) Configure DHCP to serve different subnets to different interfaces.
Forget about sending multicasts.

2) Configure Linux to bridge eth{0,2,3,4,5} and use the bridged
interface for cameras.

Both options are something I didn't know of. Time to learn something new :)

Thanks,
