Try
Hawking FR24 Dual WAN Broadband Router - US $65.00 retail
Xincom Twin WAN Router (XC-DPG402) - US $200.00 retail
Symantec Firewall/VPN200 (a.k.a. Nexland pro800Turbo) - US $900.00
retail
etc...
In these routers, they provide NAT (or Stateful inspection in Symantec kit),
DHCP Client IP addressing, Static Addressing, and DHCP server functionality.
They provide fault tolerance; and to a limited degree, load balancing across
both WAN connections.
Anyway, ask the customer does he watch the Red Green show? Does he need
duct tape? Eh? I hear you can duct tape two DSL/Cable modem routers and
create a new fangled contraption that might work.
