If you have two ISPs then you'll have two sets of public addresses
assigned to you already.  Their solution is to internally map one
address from each pool to each inside resource making them reachable
through each ISP.  Then you do DNS round robin to get "load balancing". 
I just don't like that solution because it's not as transparent to the
end user, but it does have some benefits:  No ASN needed, BGP is
unnecessary, and it conserves addresses since you won't need an entire
/24.  Unless, of course, you really do need a /24, but you probably
don't from the sounds of it.

John

Cool. I just thought it was too good to be true. I read, through a
newsgroup
search, that in order to do that, it has to act as the ns of the domain
and
that I need a separate set of public ip addresses for my network.
Basically,
it kinda works like Adapter teaming responding to ARP, sending
MACaddresses,... except on the network layer, right?

Either way, I think going with a BGP will be easier and I'm saving the
internet another set of Class C addresses.

Thanks, John
