Hello,

what else is between your router and the Internet ? Your NAT configuration is incomplete. Can you post a schematic drawing of what your physical setup looks like ?

Hello,

I have tow cisco core switch this core switch it's the first gateway, see below routing table in core switch

ip route 0.0.0.0 0.0.0.0 192.168.201.1

 the ip 192.168.201.1 this fairwall (Cisco ASA)

this routing table in fairwall route (OUTSide 0.0.0.0 0.0.0.0 192.168.200.200 1)

Hello,

it is unclear what yoour physical setup looks like, since you also have HSRP configured.

As I understand it:

Cisco 2900 --> Core Switch --> ASA --> Internet

If that is the case, you need to send all traffic on the Cisco 2900 to the Core. Is 172.16.1.1 the IP address of the Core switch ? What is 192.168.254.254 ? That is where you currently are sending all your traffic. Try and remove the second secondary static route:

ip route 0.0.0.0 0.0.0.0 172.16.1.1
--> no ip route 192.168.0.0 255.255.0.0 192.168.254.254

[mahir1234567892]

after remove the routing table --> no ip route 192.168.0.0 255.255.0.0 192.168.254.254

can't able to ping the internet router on the local network. 

Core Switch --> ASA -->Cisco 2900 --> ISP router -- >Internet.

Hello,

make sure CEF is enabled ('ip cef' globally), and that at the very least you have two static routes:

ip route 0.0.0.0 0.0.0.0 GigabitEthernet0/0

ip route 0.0.0.0 0.0.0.0 GigabitEthernet0/1
