Actually, there is no a real hardware firewall. I set the server as the firewall, and router. I could control the traffic or do some investigation if I set my server as the router. Also, the server's services is directly exposed to the WAN, so it is not needed to use port forwarding to access the server from WAN.firewall
Hey,
I plan to connect everything like this.
No, actually, I don't have that hardware. I used it to refer the WAN.satellite dish
Usually a satellite dish is connected to a pole with an azimuth adjustable bracket.
Perhaps you meant "What do you connect your LNB to?"
Thank you for your suggestion. However, have you noticed the network printer? It is one of the issues I have to use a commercial BSD. The available driver for that network printer only supports Win and the commercial BSD. If I want to print something remotely (from WAN), I have to use that BSD (I use CLI to print something like screen output directly to remote printer).I really appreciate that you were reading at the packet and frame layer to understand NAT.
I took the easy way out and use pfSense.
Like I mentioned before, you can find really inexpensive Atoms/Celerons that you can add a 4 port Intel Gigabit adapter.
That should give you 5 or 6 ports to use. One for WAN the rest your LAN.
I prefer dedicated firewall appliances with an X86 chip.
Perhaps look at PCEngines APU2. The whole rig costs under $150 for a dedicated headless appliance.
They sell it as a kit and they also will assemble and test for 5-10 bucks more. Really nice people to deal with.
It's probable I think. Satellite use radio wave (including light) to transfer packets. The most obvious example is that NASA could remotely accessed the Pathfinder who was as far as at Mars.Talking about satellite dishes, is it possible to access the Internet via satellite? I'm sure it is but how would I go about finding a satellite ISP?
