[Raspberry Pi Q&A, Help & Troubleshooting] ub3rking:
Greetings,

I use Raspbian.

I come over here, I'm a beginner, and I would like to ask for help on an issue (draft) I'm doing.

Explained below:

First of all I have Raspbian in my Raspberry Pi, then I want to do is set this as a network node to monitor through "dumpcap" packets that pass through my network, I've done I installed everything necessary in fact I've already running great, I've done through a Wireless (USB) adapter from functioning as "Access Point" wireless (so will download the files to be saved), I've come this far following this tutorial: (Photo Attached) and another pair.

The fact is that since I could configure all my peripherals, the problem lies in the following:

I need to connect from my local home router or from the Internet source (ADSL Modem), through an Ethernet cable to my Raspberry Pi (which work to record all packets My network traffic by "dumpcap") it is noteworthy that this will have perfectly configured, then I need through another Ethernet cable which my computer (PC) will be connected by a transformer USB-> Ethernet (attached reference picture), for example, that I have done and the only mistake that happens to me is that my PC does not receive Internet remains limited, in theory I need to do is that the Raspberry Pi function as a filter through which to capture packets of dumpcap store in some files (this is already done), but then the computer will connect by USB-port Ethernet continues to have internet and work perfectly as if connecting from the ADSL modem to the PC directly.

Could anyone help?

Thanks in advance.
