Email this pagehttp://serverfault.com – I use a linux Centos 6.3 as an Internet gateway with NAT. I want to allow a specific host to have access to Internet, but not with IP address, because IP may change due to dhcp, and use a rule for a specific mac address. I used the following but it does not work iptables -t nat -A POSTROUTING -o $INTERNETDEVICE -j MASQUERADE iptables -A INPUT -i $INTERNETDEVICE -m state --state ESTABLISHED,RELA (HowTos)
Email this pagehttp://serverfault.com – I want to add whitelist in my system using iptables. So I searched the web and find this: iptables -I INPUT -s 10.0.0.0/8 -j ACCEPT iptables -I INPUT -s 127.0.0.1/8 -j ACCEPT iptables -I INPUT -s 192.168.0.0/16 -j ACCEPT iptables -P INPUT DROP and it really works.

Email this pagehttp://forums.fedoraforum.org – I'm running a Fedora 17 desktop system that I've decided to put an OEL 6 virtual machine on. I built the VM first with virtual network NAT the default but discovered that only the host could communicate with it. After reading the available documentation (which I probably should have done first) I found that I needed to use a bridged network on the host so the VM would be available on my LAN. (HowTos)

Email this pagehttp://serverfault.com – I've got a small network, two interfaces, eth1(local, internal range 192.168.150.0/24) and eth0 external, static ip. I wish to set up nat forwarding for the internal network but allow them to only connect to an external server 209.60.x.x and reject connections to all other external ips. How do i only allow forwarding/nat to ip 209.60.x.x ? (HowTos)
