I have issue with that in VirtualBox, I have lab in VirtualBox like this:
VBOX ( CentOS(2 nic’s, eth0 -> NAT and eth1 -> internal), 3 client’s)
CentOS:
eth0: have dynamic IP, eth1 have static IP, CentOS can access to internet but other client can’t, I setup in them default gateway and static IP but it doesn’t work.

But, all the settings disappear if network is restarted.

Hi,
I recently purchased a sony bluray player and wanted to connect it to the internet through an old dell wireless G laptop that is no longer being actively used. The setup was
BluRay(Ethernet port) -> Dell Laptop (Ethernet Port) -> Dell Laptop (Wireless G card) -> Wireless G Router (Integrated ADSL modem/wireless AP/router) -> Internet.
Tried this tutorial but could not get my setup working. I disconnected my bluray and hooked up an apple macbook to the dell laptop for testing. I was able to ping the dell ethernet port (eth 0 @ 192.168.1.254) and the dell wireless card (eth1 @ 10.0.0.7). The wireless network is setup to obtain an IP address using DHCP from my wireless router. I was almost ready to give up when I found a different website with a tutorial. The only additional command that seemed to get my connection to work is:
echo 1 > /proc/sys/net/ipv4/ip_forward
After executing this command, my apple macbook and the bluray were able to connect to the internet just fine.
I can’t figure why the additional command is required and why it’s missing from the script. Oh, and I also had to manually setup the ethernet card address like so:
ifconfig eth0 192.168.1.254
I hope this helps someone!

Good one. But unfortunately there is no way of controlling the users who use the connection via the server.

I advice you use try out traffpro. A open-source monitor and security system. Allows you to have a more easier way of setting up internet sharing.
