I added a proxy-arp enty:
source {rule-set my-lab-internal {from zone lab-internal;to zone untrust;rule
my-lab-inet {match {source-address192.168.2.0/26;}then {source-nat
{interface;}}}}}destination {pool lab-plasma {address 192.168.2.2/32 port
8080;}rule-set lab-nats {from zone untrust;rule lab-plasma-1 {match
{destination-address 4.5.32.16/32;destination-port 8080;} then {destination-nat
pool lab-plasma;}}}}proxy-arp {interface reth0.0 {address {4.5.32.16/32;}}}
The translation hit counter from 'show security nat destination rule all' does
not increment so I'm still not hitting the NAT rule. I have the appropriate
security policy rules between the untrust and lab-internal zones to allow 8080
inbound and anything outbound.

We use routed ranges to NAT a few hosts. The key for us was configuring
proxy-arp on the untrust interface for the IPs.

I've seen plenty of examples of a static NAT where the SRX has a public IP

has an IP range routed to it.
SRX Public IP: 4.5.6.60/30Routed IP range (via the public interface)
4.5.32.16/28Trusted zone: 192.168.2.1/26
show configuration security nat (hopefully this will display properly)
source { rule-set my-lab-internal { from zone lab-internal; to
zone untrust; rule my-lab-inet { match {
source-address 192.168.2.0/26; } then {
source-nat { interface; } }
} }}destination { pool lab-plasma { address 192.168.2.2/32 port
8080; } rule-set lab-nats { from zone untrust; rule
lab-plasma-1 { match { destination-address
4.5.32.16/32; destination-port 8080; }
then { destination-nat pool lab-plasma; } }
}}
The result of this configuration is that no NAT occurs. But if I change the
destination-address to the SRX's external IP (4.5.6.60) it works just fine.
