Q. If I have a Windows machine with a virtual linux based firewall appliance inside of it, I know how to protect the host machine with the firewall. How do I protect the other machines on the LAN using the virtual appliance ? Would I only have to set the "Gateway" setting of the other machines to the address of the virtual machine ?
A. Yes, and set their firewalls to block anything not comming from the appliance.
I have activated a port for a office but have internet connection problems?
Q. Recently I have activate a port for a office room and i'm gettting internet connection but if i type something in search it gives me connect to office or offline. I'm currently running a linux firewall do i need to do some setting? or what should i do to fix it?
A. Make sure the port you specifies is not interfering with other services that is using the same port. You can also flush all the port to see which port is having problem. Also make sure your internet daemon is running.
You can always ping your router or any outside network to see if it has internet connection.
I hope this help.

Linux Firewall on a home network?
Q. What would be the use of a linux firewall in a home network? Is there any point in making one?
A. The primary purpose would be to learn more about how firewalls, routers and IPTables work. It used to be that it took some big iron to run firewall and router software, "back in the day"
Today, of course, you can buy a $40 home router that does most everything you need
Here are some other reasons to set up a Liniux
1. you want to monitor all traffic in and out of your home network. Using a Linux machine as a router/firewall allows you to tap the Ethernet port with Wireshark and sniff the traffic coming to and from the whole network, not just one machine..
2. You want complete control of what all the machines can do and when they can do it on the network.
Home routers give you some control.
A Linux firewall/router gives you control that only a high priced router can give you.
Bandwidth allocation and limits are not available on low end home routers. Linux would give you the same controls as a full business router costing $500 or more.
But these days - mostly for fun and to learn
