I understand. So your reason for having mutliple WANs and firewalls is purely redundancy?

No load balancing or better security in mind?

Doing an nslookup on www.google.com returns multiple addresses, so I assume there's a way of stacking them in DNS?
DNS is a very complex technology -

When you are talking about incoming access from the web - I dont believe there is much for automatic redundancy. You would be able to setup a failsafe that you must manually 'enable' if there are problems with the primary link..... but I am not sure what the point will be, especially when you weight the cost-benefit scenario.

Just go with a good ISP with a decent business plan and the need for redundancy should be minimal.

We have mutliple ISP's/WAN but specifically so we can access certain clients at faster speeds, and one plan is for high speed net access (small d/l limit) and the other plan is a slower speed but allows a huge amount of data to go between LAN & WAN.
