[CentOS] centos as a firewall help
Hello all, first of all i'd like to wish you all happy holidays, and a merry belated christmas.

The reason I ask is you only showed the firewall rules not the nat table. Otherwise you need to setup nat masquerading to allow other connections out. Have you though of virtualizing your firewall with a purpose built distribution like Vyatta or pfSense? I have taken this approach with my setup. I find it makes updates easy and provides better uptime.

I can vouch for the Sun Quad Fast Ethernet (PCI) cards. Quite a while back a few co-workers and I had split a small lot of them from eBay the broke down to roughly 8 or 9 bucks with shipping.

When dynamic dns updates are turned on dhcpd can update a zone in named with the hostname for the ip handed out. The benefits of running your own dns server is that you can access systems in your network by name and not ip.

The virtual disk works just like a hard drive. If you create a 80GB hard drive it reports it to the guest OS as a 80GB hard drive. The "don't allocate the entire disk now" message is about how the host OS creates the virtual disk file. If you don't allocate it up front you end up with a sparse file. du and df commands will show the space actually used. ls will show you the actual file size which would be 80GB.
