AP Public IP PAT over Internal network

Hi All,

Need a word of advice.
I have the following topology in my network:

AP (10.10.10.1)–(10.10.10.2) Mtik —(VLAN 100 192.168.1.1)–(VLAN 100 192.168.1.2)Edge R— Core Claud — Internet

I was given a public IP /32 to be used as PAT over the Mtik router.
But my outside interface is the 192.168.1.2 over sub interface VLAN 100

How should i configure it and route it so users over the AP will browse the Internet.

Should i use loopback address? Need your advice please.

Thank you in advance,
Shubi
