I have a server  with eth1 having a full IP address, DNS, gateway and proxy name connected to the university internet/intranet provider and eth0 IP 192.168.1.2 connected by a gigabit switch with two nodes 192.168.1.3 and 192.168.1.4. All three running the latest full Debian Wheeze installation from DVD with all components available.I have configured this subnet using interfaces file using only static IP addresses and netmask like this iface eth0 inet staticaddress 192.168.1.2netmask 255.255.255.0with extra set of parameters for eth1 on server which is able to access internet through this card.I can not arrange an internet access for the nodes through server's eth1 using iptables or any other tools available for look up on the Internet.Any help with complete script example using iptables and/or additional features/lines to introduce to the interfaces files on two nodes taking into account all these proxy and fixed university ipadress configurations for the outer network on eth1?SSH is working just fine on this subnet. My server can access Internet as well.I'm reading this tutorial.May be I misconfigured all these DHCP, NSF, NAT etc though I've never touched them directly and SSH is working just fine across this subnet.
