I have a Cisco Router configured  with Nat Static  translating  internal network to another subnet to avoid subnet conflict

this is working fine, however internet browsing is not working with the  overload statement. snapshot configuration as follows:

Router#

interface GigabitEthernet0/0
 mtu 1400
 ip address 184.170.143.94 255.255.255.240
 ip nat outside

!

interface GigabitEthernet0/1
 ip address 192.168.18.250 255.255.255.0
 ip nat inside

!

ip nat inside source list 1 interface GigabitEthernet0/0 overload
ip nat inside source static network 192.168.18.0 172.19.18.0 /24 extendable

!

access-list 1 permit any

Router# show  ip nat translation:

It's not clear what the static NAT is meant to be doing so this may not be the full solution.

You cannot use "any" as the source IPs in your NAT acl so you need to reference the real IPs.
