Not able to ping secondary ip of router interface from different vlans

Hi 

I am facing issue with Router secondary ip address of interface.

ROUTER<---VLAN1 ---->Core<------VLAN3---> L2_SWITCH----(VLAN3_PC)

 

interface GigabitEthernet0/0
 description ***** LAN_XXXL *****
 ip address 172.16.33.12 255.255.254.0 secondary    ( Local IP )
 ip address XXX.XXX.XXX.225 255.255.255.240       ( Public Ip )
 ip flow ingress
 ip nat inside
 ip virtual-reassembly in
 duplex auto
 speed auto 

 

Router has public ip as primary ip on LAN interface and it has secondary ip address of Vlan 1.

From core switch im able to ping router secondary ip but from VLAN 3 machine im not able to ping router secondary ip.

My ping tracert drops at core.
