Per a previous post here I've been working on Wireshark and ufw within linux. Although I haven't been able to master these two technologies (there is more than I expected and not as much free time as I need) I have another issue after seeing what Wireshark is capable of. My employer has given me one of their laptops to interface with their network. Do to their security policies the use of this laptop is non-negotiable. So it uses my home network. My setup is very basic. I have a router-DSL-modem setup from ISP. The employer laptop warns that it can monitor all computer activity on use, but If I'm in super paranoid mode it seems possible that the employer could have something like Wireshark on the laptop and be monitoring all my network traffic. Some ideas: 1) I can already anticipate that one solution is "use a VPN" to encrypt all my traffic on other machines. While I could research a setup for my Linux computers using my network I'm not sure I have control over Roku, Amazon Kindle and other proprietary devices I may buy in the future. With that said, one has to wonder with the information collecting going on these days whether these types of devices have their own sniffers. 2) I've wondered if connecting the employers laptop via cat-5 cable as opposed to wireless would eliminate sniffing but I know enough now to realize that the hub or switch that the ISP router-DSL-modem uses might still share broadcasts across that. 3) I have an old WRT54GL with Tomato firmware installed that I figured I could plug into ISP router-DSL-modem via cat-5 then have employer laptop either use that WiFi or another cat-5 from WRT54GL to employer laptop. Other devices on my network would use the ISP router-DSL-modem SSID or I may need to purchase another router and hopefully not get too much of a problem from the ISP router\modem for having two routers and two networks running through it? I've already been looking into experimenting with OpenWRT and this old WRT54GL, from what I've read, seems to barely have the hardware to support the newer version. I've done some research on OpenWRTs website in regards to the best router but I've also consider the Raspberry Pi as a possible solution here since it seems like you can configure it to do almost anything. This is really a separate question from the "sniffer" protection I'm looking for but I do like the idea of having a Linux based router that I can install software packages on and use the command line to administer so I can configure firewall and log all network traffic for all devices on the network.
