Which of the protocols below is used by Netinstall?
alasan:
berkaitan dengan tema kali ini apabila melihat sekilas perbedaan sistem operasi yang digunakan RB260GS/GSP yaitu SwOS tetap bisa di install ulang, namun untuk langkah-langkahnya tidak sama dengan cara install ulang RouterOS. Berbeda dengan RouterOS yang bisa menggunakan aplikasi netinstall untuk install ulang sistem operasi, pada SwOS ini kita bisa install ulang menggunakan BOOTP (Bootstrap Protocol).

PPPoE server only works within one Ethernet broadcast domain that it is connected to. If there is a router between server and end-user host, it will not be able to create PPPoE tunnel to that PPPoE server.
alasan: PPPPoe bisa pakai tunnel

Chain & Action
Firewall filter rules are organized in chains
There are default and user-defined chains
There are three default chains :
input – processes packets sent to the router
output – processes packets sent by the router
forward – processes packets sent through the router
Every user-defined chain should subordinate to at least one of the default chains

The correct order for PPPOE discovery stage is
PPPoE Operation
PPPoE has two distinct stages(phases):
Discovery phase;
Session phase;
Discovery phase
There are four steps to the Discovery stage. When it completes, both peers know the PPPoE SESSION_ID and the peer's Ethernet address, which together define the PPPoE session uniquely:
PPPoE Active Discovery Initialization (PADI) - The PPPoE client sends out a PADI packet to the broadcast address. This packet can also populate the "service-name" field if a service name has been entered in the dial-up networking properties of the PPPoE client. If a service name has not been entered, this field is not populated
PPPoE Active Discovery Offer (PADO) - The PPPoE server, or Access Concentrator, should respond to the PADI with a PADO if the Access Concentrator is able to service the "service-name" field that had been listed in the PADI packet. If no "service-name" field had been listed, the Access Concentrator will respond with a PADO packet that has the "service-name" field populated with the service names that the Access Concentrator can service. The PADO packet is sent to the unicast address of the PPPoE client
PPPoE Active Discovery Request (PADR) - When a PADO packet is received, the PPPoE client responds with a PADR packet. This packet is sent to the unicast address of the Access Concentrator. The client may receive multiple PADO packets, but the client responds to the first valid PADO that the client received. If the initial PADI packet had a blank "service-name" field filed, the client populates the "service-name" field of the PADR packet with the first service name that had been returned in the PADO packet.
PPPoE Active Discovery Session Confirmation (PADS) - When the PADR is received, the Access Concentrator generates a unique session identification (ID) for the Point-to-Point Protocol (PPP) session and returns this ID to the PPPoE client in the PADS packet. This packet is sent to the unicast address of the client.
