A NAT rule similar to the following would accomplish your goal of outbound dynamic translation, assuming you wanted to use PAT (most likely if you only have a few public IPs):
services { nat { pool nat-pool { address 50.0.0.1/32; port automatic } rule nat-set-outbound { match-direction output; term 1 { then { translated { source-pool nat-pool; translation-type source dynamic; } } } } } } Notice I used a pool here. This is not necessary but allows for future scalability if you get additional public IPs and want to add them to the pool. Also notice that I have not specified a from clause. This will essentially match on *all* outbound flows. If you want different behavior you should specify the match conditions appropriately.
