Have an issue with a new ASA 5506W - setup allows internet access to all systems behind it except for the ones with a static NAT - we have separate IP addresses assigned to 2 servers, all the access rules are in place but neither of them have internet access (LAN access is fine on all systems). Not sure what we're missing - config is:

nat (any,outside) dynamic interface
nat (inside,outside) source dynamic obj_any interface
Start with simple nat rule and try it works, if basic rule working then start building complex rule, by understand each rule before applying.

You are using object NAT which is bidirectional by default (but does get applied with lower preference)
can you show how your servers get NATed to ouside (internet) by using packet tracer and paste a screen shot of the NAT applied (or packet trace output(.
