Multiple Ethernet ports on the raspberry pi

Former Member

Hi all,

i'm interested in getting an additional Ethernet port hooked up to the raspberry pi.

the project is to create a home server (nas) and router from a raspberry pi, and I don't want wifi.

 

the final box should have both USB ports free for attaching multiple drives, or a drive and a printer(these are externally powered, not to be taken into account powerwise, the Ethernet port is the main issue).

the pi should be powered by an external power supply (although managing to power it from a pc's USB port will be awesome (using the console cable)

 

future upgrades might include replacing the second Ethernet port with an adsl modem or with a 3G modem.

 

i'm have experience with Linux. the electronics is the part I don't remember much.

 

I've searched and can't find an Ethernet add on board. I can't even find a USB Ethernet adapter.

I reckon it's because lack of interest though, and not cause it's not possible.

 

to make a long story short, is it at all possible?

 

thanks

  • Can the PI not have its Ethernet port multi homed

     

    ie, 2 IP addresses on one port, Windows can and most versions of Unix in the past so even though I have not tried it on the PI, im sure it can be done

     

    this would probably give the fastest Ethernet speeds but you would still need the external Ethernet switch or two cheap hubs working in reverse etc to support it

    Sure it can. (be multihomed).

     

    About the performance... I have a 15Mbps ADSL connection. So if one of the ports is limited to 15Mps or if the total is only 115Mbps, that' be fine. In fact, if the raspberry pi is the router, a total of around 30Mbps would suffice.

     

    Leaving the pi on (e.g. powered by the standby 5V power of your PC?) and a few storage devices connected can leave you with a powerful setup. long-term-downloads can continue all day without using much power. The pi might control other stuff, e.g. power on the PC when ordered to do so over the internet. etc. etc.
