ASA PAT no translations in only one interface.

Hello there,

Only one interface is not being translated to the outside (G1/2 - ESXi)------PAT---->(G1/1 - Dflt-Gw)

The other inside interfaces HOME LAB and DNS can get to the internet with no problem,

The ASA and hosts on other interfaces (pre-NAT) can be reached from the ESXi VMs,

When doing a packet tracer test on the ASA comes back with a sucesful message but as we can see no hits are being translated.

No ACLs configured on this device, only security levels and NAT/PAT to the outside,

Let me know if you'd like more info,

Thanks in advance for any comments on this,
