Ethernet 的 MTU 是 1500, PPPoE 是 1492 (Windows 下的 PPPoE 是 1480)
只有在特殊狀況時才需要修改 MTU, 例如連不上某個點

Windows 2000/XP
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\{網卡的GUID}]
新增 DWORD 值, 名稱 MTU, 值 1492 (十進位)
網卡停用、啟用

Windows Vista/7
netsh interface ipv4 set subinterface "區域連線" mtu=1492 store=persistent
網卡停用、啟用

Linux/FreeBSD
ifconfig [interface] mtu 1492

ref. Windows XP 的 TCP/IP 及 NBT 設定參數
