Chris 🇹🇼 | Telegram 尼有事嗎 => YSITD: The maximum MTU for Ethernet connections on SonicWALL devices is 1500 bytes (Ethernet maximum MTU size). Having an MTU of 1500 allows for 1460 bytes of data payload, 20 bytes of TCP header, and 20 bytes of IP header. With PPPoE connections, the PPP and PPPoE header increases the frame size by 8 bytes, so we must lower the MTU to 1492. With the Ethernet header added to this, we get a frame size of 1518 bytes. 1492 + 8 + 18 = 1518 bytes #5770c9e42a8ebff3e856c4ed
