Hi Paul,
This is a very basic and very important question.
I assume that you have 2 wan connections (on serial or Ethernet) from your
ISPs, and your local network is connected through a different Ethernet
connection.
You need to do these steps :
1) you need to create 2 static routes to each ISP's default GW IP address.
(usually the default GW IP address is static even if you are receiving IP
settings through DHCP from your provider). If you don't want to use static
routes, the router may use both default gateways received by DHCP on each
wan link (I'm not sure its working or not in this way).
2) I assume (95%) you don't have your own IP addressing and AS and BGP. So
you need to do NAT through each WAN link. You MUST use NAT with route-map to
NAT with appropriate IP address on each link.
3) the CEF will load balance your traffic based on destination.
