Share internet thru another ethernet port - Raspberry Pi Forums

hi guys,

first post here, , i'm new on raspberry world!

want make question: possible connect usb-ethernet adapter raspberry, , make works wired router? explain why need this:

make rasp work router receiving connection isp using built-in ethernet port (via dhpc), , share connection thru usb-ethernet adapter buy. need this, because want rasp part of private network , wifi not option me!

try draw scheme:

have today:

code: select all

isp --1--> router --2--> laptop, phone, etc

connection 1 happens thru dhcp via ethernet cable
connection 2 happens via ethernet cable, or wifi.

that want do:

code: select all

isp --1--> rasp --2--> router --3--> laptop, phone, etc

connection 1 remains dhcp.
connection 2: rasp should connect internet, , share connection router via ethernet cable (that why need 2 ethernet port)! wifi not option.
connection 3: can via ethernet cable or wifi.

possible? if yes, there how-to document can follow?

how isp provide internet (adsl, cable etc.)? set missing modem typically required domestic internet provided in uk - not sure if country has different options.

don't state why want this. far can tell seeking place r-pi in between home router , internet, bottleneck given limited networking speed offered raspberry pi.
