Not everything you will find in the documentation below works on the Vyatta boxes we are using in the lab. The syntax for some of the commands shown are different from what works on our Vyattas. I am listing the documentation in a rough order of correctness and applicability with respect to our Vyattas:

Vyatta Quick Start Guide

Vyatta NAT Reference Guide

Vyatta Services Reference Guide

Vyatta OFR Configuration Guide

Vyatta Static Routing Reference Guide

Vyatta RIP Reference Guide

Vyatta Firewall Reference Guide

The set of tutorials at the link below are a little dated, in the sense that (as with some of the documentation above), the syntax of some of the commands given in them is a little different for our Vyattas. Nevertheless, the tutorials are quite useful and worth taking a look at:
