multiple public IP subnets on Cisco 1941 router

hello everyone.

i have a 1941 router, the ISP has provided me a public IP configured on a sub interface as below

interface GigabitEthernet0/0.1179
 ********************************************
 encapsulation dot1Q 1179
 ip address x.x.x.38 255.255.255.252
 ip nat outside
 ip virtual-reassembly in

then we add another subnet  y.y.y.8/255.255.255.252, and configured 1 IP on  the router on another sub interface as below

interface GigabitEthernet0/1.5
**********************************************
 encapsulation dot1Q 20
 ip address Y.Y.Y.10 255.255.255.252
 ip nat outside
 ip virtual-reassembly in

the second IP in the subnet "Y.Y.Y.9/255.255.255.252" , i assigned to a local Server in my LAN

 

i can ping the Local server public IP "Y.Y.Y.9" from inside the router interface and the server can ping the Router public IP

 

and also i can access the Router public IP "Y.Y.Y.10" from internet outside my network but cannot access the public IP assigned to the server .

 

can you please help me to find a solution for this.

 

Thanks

I don't think you need an ip nat outside for your GigE0/1.5 interface.

Also, server should have default gateway pointing to y.y.y.10

HTH.
