There is a specialized case of Source NAT called masquerading: it should only be used for dynamically-assigned IP addresses, such as standard dialups (for static IP addresses, use SNAT above).
為什麼他建議Masquerading適用於dynamically-assigned IP addresses
如果Masquerading用於static IP addresses會有什麼結果?
差異在哪裡?

# Turn on IP forwarding
echo 1 > /proc/sys/net/ipv4/ip_forward
為什麼需要這一行?
有更詳細的說明嗎?
架設nat有無可能被當作跳板呢(被同網域的設成gateway)?
