You're talking about industrial-grade connections.  Mine were more
like the home ones: two small ISPs, one with local Ethernet network
and one with DSL.  They will never play with each one in my situation,
moreover, they should not even notice that my host is dual-homed.
So, that was the cheap way to be online most of the time.

Thanks for the education!  I have only one question: what it 'Yugo'?
I had not found it in nearby dictionaries ;))

Thanks again!
