You are using three different IP addresses that are dynamically (OK. If you
insist statically) assigned to three different links. But how can I reach
your web server ?
This is different from the corporate world to have the same IP coming in
from different links.

Maybe you are willing to black-hole some /24 block like eBay ?

In this SOHO situation you don't need a seperate entry in the 
global routing table. Also the point is two links (phone line won't
die the same time as the satellite, will they ?)

This is going backward to ask company to have full mesh among all the ISPs ?
