for basic loadbalncing

you can do it by using equal cost route

i will assume that you have deault static route to the ISP

if you have two ISPs or link fo rhe internets you can configure two static route with the same AD each one point to one of the links ( next hop)


and also you need to consider the NATing if you are doing the nating in the router for te internet traffic


see the bellow document that may help you to understand some concepts and configurations:
