ip nat inside source and ip nat outside source
Routers are inspecting incoming and and outgoing packets if they are configured to do so.
The "ip nat inside source" means to inspet an incoming packet originated from an "outside" interface (configured as: ip nat outside) towards an "inside" interface (configured as: ip nat inside) and act accordingly.
The "ip nat outside source" means to inspet an outgoing packet originated from an "inside" interface (configured as: ip nat inside) towards an "outside" interface (configured as: ip nat outside) and act accordingly.
