Failed to replace Static NAT with PAT on Cisco router

iwrite

Tried to do NAT on Cisco routers, and successfully set up Static NAT, as below configuration section (1).
But issue comes when I tried to configure PAT by simply replacing static nat command with PAT command and related access-list command, as shown in configuration section (2), nothing is showd up with command "sh ip nat translations".

I'm wondering if there is anything else need to set up beside the PAT and access-list command?

1) Router configuration of Static NAT, can ping and telnet from inside hosts to outside hosts:

!Inside port configuration
interface Ethernet0/0
ip address 10.1.234.2 255.255.255.0
ip nat inside
!
!Outside port configuration of p-to-p frame-relay
interface Serial0/0
no ip address
encapsulation frame-relay
no arp frame-relay
no frame-relay inverse-arp
!
interface Serial0/0.12 point-to-point
ip address 210.1.12.2 255.255.255.0
ip nat outside
ip virtual-reassembly
frame-relay interface-dlci 201
!
!Static NAT configuration
ip nat inside source static 10.1.234.3 210.1.12.3

(The output of "sh ip nat translations" looks good.)

2) Remain all configuration un-changed, except replacing “ip nat inside source static 10.1.234.3 210.1.12.3” command with below 2 commands to change it to PAT from Static NAT:

!PAT configuration
access-list 1 permit any log
ip nat pool globalnet 210.1.12.3 210.1.12.3 netmask 255.255.255.0
ip nat inside source list 1 pool globalnet overload

!Outout is empty of below command：
r2#sh ip nat translations

r2#

Before doing anything else, you should check if traffic has occurred. If not, no translations have been made, and so list will be empty.
