Cisco 2960 switch NAT

[Kane Smith]

Hi all, I have a Cisco 2960 switch running IOS 15.2(7) E7. I configured NAT overload.

Straight forward config:

interface Vlan150
description INSIDE-LAN
ip address 10.150.0.254 255.255.255.0
ip nat inside
!
interface Vlan192
description OUTSIDE-LAN
ip address 192.168.0.254 255.255.255.0
ip nat outside
!
ip access-list standard NAT-LIST
permit 10.150.0.0 0.0.255.255
!
ip nat inside source list NAT-LIST interface Vlan192 overload

NAT doesn't work when a device on the 10.150.x.x network (default gateway is 10.150.0.254) tries to reach the Internet.

However, if I source a PING from 10.150.0.254, it works fine:

SW1#ping 8.8.8.8 source 10.150.0.254
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 8.8.8.8, timeout is 2 seconds:
Packet sent with a source address of 10.150.0.254
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 16/20/25 ms
SW1#

SW1#sh ip nat translations
Pro Inside global Inside local Outside local Outside global
icmp 192.168.0.254:1024 10.150.0.254:3 8.8.8.8:3 8.8.8.8:1024
SW1#

I have verified using traceroute that the PC on the 10.150.x.x network is indeed going to SW1 in order to get to 8.8.8.8.

Any ideas please?

Hello @MHM Cisco World 
FYI its  due to having dual cco accounts and flipping between them, as such my browser(s) cannot keep up.

cheers..

Yes. That is correct. Its in a lab environment. Does everything we need but NAT. Didn't really want to add a router to perform just one function.

ip access-list standard NAT-LIST
permit 10.150.0.0 0.0.255.255

Correct this to be 

ip access-list standard NAT-LIST
permit 10.150.0.0 0.0.0.255
