[ale] two connections to internet??

[Leonard Thornton]

Pack rat?  Yep....that's me....I got equipment so old it's mentioned 3 
times in the Old Testiment.

 From the initial description Gary provided, I don;t think load 
balancing / failover is much of a consideration.  You are correct, 
however, in your observation that routing is not easy.  Considering that 
all PC's on the internal lan will point to the firewall as their 
gateway, the firewall much handle the appropriate routing to seperate 
the traffic destined for the DSL or cable side.

One trick, though I cannot testify to it's workability, would be to 
assign multiple IP addresses (2) to the adapter attached to the local 
network.  Then, use routed to set each of these addresses to point to 
either the cable or the DSL for their default gateway.  The machine on 
the internal LAN could then be assigned either IP address as their 
default gateway depending on the route you wish for them to take.....

OR....I could be suffering delusions from the medication I am taking for 
this flu......you tell me...
