各位前輩好！

小弟透過網路上NAT、PAT的各種教學，最終都無法ping到ATU的default gateway，以下用靜態NAT作範例，希望前輩能指出錯誤的地方，謝謝！

簡單板：
interface FastEthernet0/0(路由器接ATU)
ip address 192.168.100.50 255.255.255.0
ip nat outside
!
interface FastEthernet0/1(路由器接PC)
ip address 192.168.0.1 255.255.255.0
ip nat inside
!
ip nat inside source static 192.168.0.2 192.168.100.50
ip route 0.0.0.0 0.0.0.0 192.168.100.1
