[Lamobo R1 - ARMBian 5.0 Jessie Server - Network expert please help]

Thomas is correct.

 

You have configured your Lamobo-R1 as a router. If you go this way then you have to:

 

1. Run DHCP/DNS server (eg. dnsmasq) on the Lamobo-R1 to provide a network for the routed network (laptop side)
2. Configure routing on the Lamobo-R1 (not NAT!) so that packets traverse to/from the 192.168.1.0/24 network (BBox2 side) and the routed network (laptop side)

 

Simpler solution, which is from Thomas - configure the Lamobo-R1 as a bridge. Then DHCP assignment and DNS service will be provided by the Bbox2. If you do this, you don't need ebtables - unless you want to control access to the bridge.

Sure I do --I remember also the nice ebtables stuff to tunnel AppleTalk through IP

 

Regarding dropped RX packets unfortunately no idea since I gave up on this device completely and used the Wi-Fi only once to have a short laugh and drop the idea to use it: The best you can do with the Wi-Fi module is to unsolder it: http://forum.armbian.com/index.php/topic/372-hardware-mod-bpi-r1/

 

Thanks, Thomas for the suggestion! I know someone with a solder station - I think I will try the hardware mod. At worst I lose ~$30.

 

Because of a traumatic event, I lost most of my memory of events from the early 90's to mid-2000's, including various Linux networking projects. Thanks to low-priced SBCs, I'm slowly getting back in the game .....

Hello -

 

First post to this forum - hope it isn't out of line.  I have been running Armbian 4.5 on my Lamobo-R1 for a few months.  WiFi has been stable, in that connections do not drop, as long as I disable 802.11n. 

 

However, there are two issues that may be related:

1) Throughput is crap - I max out at 8-10 Mbps - which fortunately is sufficient for my needs

2) Huge number of dropped RX packets.

 

Anything I can do to improve this? I've cut & paste details below.

 

Regards and thanks,

Ashok

 

P.S Thomas - if you read this post, perhaps you remember me from more than a decade ago on the netatalk list?
