Feasibility question regarding Ethernet gateway

mithra last edited by

Hey guys, a quick question for you please :

I've seen a lot of mention of how to build wireless gateways, but what I'm wanting to build I can't seem to find documentation for :

I want to create a wired Ethernet gateway for my Windows PC that will be able, via programming, to directly handle / filter each packet that goes out from my PC to the Internet. So think of it like a hardware version of Wireshark.

For example, if the gateway address of my router is 192.168.1.254 (typical) and I plug my arduino into my switch, let's say it pulls an IP address of 192.168.1.70. What I'd like to do is configure my PC to have 192.168.1.70 as its gateway, so that all my traffic gets pushed through the arduino before it gets to the net.

Is this feasible, has anyone done this already? All feedback is appreciated, thank you!

@andriej Hi, I had problem using the main branch mysensors/Raspberry, that because of the bit-field struct (header_s) in Sensor.h They will get packed in different order on the arduino compared to the RPi (at least with my compiler, gcc). In order to fix this I created the 1.4dev branch. It uses full bytes instead of the bit-fields, but you need (of cause) to compile both the sensors (arduino) and the gateway (RPi) using the 1.4dev branch. We need to fix this in the main branch later on (and use the same files as in mysensors/Arduino/libraries/MySensors)

Of possible interest: Here's a guy who is building an inexpensive open source ethernet controller for stepper motors: What happend to Ethersweep? Project Update! – 12:36— Neumi If you listen to the end, it's revealed that there is now generous funding available which allows people to do this kind of open-source development as a full time job, which is what he is now doing. For that reason, I think there's a good chance he will complete his project within the allowed 6 months., and so by the deadline it will likely be nicely polished.

Hi everyone Which MySensors lib did you use? The 2.3.2 or the delevopment version? I tried to fix the errors, but they don't appear in the development branch. Only another error which i fixed. Regards, Edi

@skywatch said in Awesome tip: run LinuxFX instead of Windows!: @NeverDie Thanks - Interestingly they show a free version on their site still. Did they revert due to bad publicity? https://www.linuxfx.org/ I stopped following it, but I seem to recollect that the free version was noticeably missing things--otherwise, who'd buy the paid-for version? Anyway, its standing on Distro-watch has fallen considerably. It may seem unfair to niche distros, but I think it's generally better to stick with the more popular distros, unless you have good reason to choose otherwise.
