This is my router config:
interface GigabitEthernet0/0.168
description Security Desk
encapsulation dot1Q 168
ip address 192.168.0.1 255.255.255.0
ip flow ingress
ip flow egress
ip nat inside
ip virtual-reassembly in
ip nat inside source route-map SECURITY_DESK interface GigabitEthernet0/0.168 overload
route-map SECURITY_DESK permit 10
match ip address 168
ip route 192.168.0.0 255.255.255.0 PUBLIC_IP
access-list 168 permit ip 192.168.0.0 0.0.0.255 any
It's building translations, but somehow the traffic is not leaving the router for the internet. What am I doing wrong?
EDIT: I notice I am getting a 192.168.0.1 address for my inside global instead of a public IP. Not sure why that is happening.

You need to use
Ip nat outside
Not
Ip nat inside
Under this interface

Thanks, but I caught was I did. The inside interface is correct, however; I needed to nat back to my outside interface.

I dont get your comment
It mandatory to use
Ip nat outside
Under interface use for NAT overload

Hello
Example base on your OP:
int x.x
no shut
int x.x.168
encapsulation dot1Q 168
description WAN
ip address 1.1.1.1 255.255.255.252
ip nat outside
int x.x
description LAN
ip address 192.168.0.1 255.255.255.0
ip nat inside
ip access-list extended 168
permit ip 192.168.0.0 0.0.0.255 any
route-map LAN
match ip address 168
ip nat inside source route-map LAN interface <WAN> overload
ip route 0.0.0.0 0.0.0.0 <WAN interface> 1.1.1.2
