Linux Demilitarized Zone (DMZ) Ethernet Interface Requirements and Configuration

the ori : http://www.cyberciti.biz/faq/linux-demilitarized-zone-howto/

Q. Can you tell me more about Linux Demilitarized Zone and Ethernet Interface Card Requirements for typical DMZ implementation? How can a rule be set to route traffic to certain machines on a DMZ for HTTP or SMTP?

A. Demilitarized zone, used to secure an internal network from external access. You can use Linux firewall to create DMZ easily. There are many different ways to design a network with a DMZ. The basic method is to use a single Linux firewall with 3 Ethernet cards. The following simple example discusses DMZ setup and forwarding public traffic to internal servers.

Sample Example DMZ Setup

Consider the following DMZ host with 3 NIC:
[a] eth0 with 192.168.1.1 private IP address – Internal LAN ~ Desktop system
[b] eth1 with 202.54.1.1 public IP address – WAN connected to ISP router
[c] eth2 with 192.168.2.1 private IP address – DMZ connected to Mail / Web / DNS and other private servers

Routing traffic between public and DMZ server

To set a rule for routing all incoming SMTP requests to a dedicated Mail server at IP address 192.168.2.2 and port 25, network address translation (NAT) calls a PREROUTING table to forward the packets to the proper destination.

This can be done with appropriate IPTABLES firewall rule to route traffic between LAN to DMZ and public interface to DMZ. For example, all incoming mail traffic from internet (202.54.1.1) can be send to DMZ mail server (192.168.2.2) with the following iptables prerouting rule (assuming default DROP all firewall policy):

### end init firewall .. Start DMZ stuff ####
# forward traffic between DMZ and LAN
iptables -A FORWARD -i eth0 -o eth2 -m state –state NEW,ESTABLISHED,RELATED -j ACCEPT
iptables -A FORWARD -i eth2 -o eth0 -m state –state ESTABLISHED,RELATED -j ACCEPT
# forward traffic between DMZ and WAN servers SMTP, Mail etc
iptables -A FORWARD -i eth2 -o eth1 -m state –state ESTABLISHED,RELATED -j ACCEPT
iptables -A FORWARD -i eth1 -o eth2 -m state –state NEW,ESTABLISHED,RELATED -j ACCEPT
# Route incoming SMTP (port 25 ) traffic to DMZ server 192.168.2.2
iptables -t nat -A PREROUTING -p tcp -i eth1 -d 202.54.1.1 –dport 25 -j DNAT –to-destination 192.168.2.2
# Route incoming HTTP (port 80 ) traffic to DMZ server load balancer IP 192.168.2.3
iptables -t nat -A PREROUTING -p tcp -i eth1 -d 202.54.1.1 –dport 80 -j DNAT –to-destination 192.168.2.3
# Route incoming HTTPS (port 443 ) traffic to DMZ server reverse load balancer IP 192.168.2.4
iptables -t nat -A PREROUTING -p tcp -i eth1 -d 202.54.1.1 –dport 443 -j DNAT –to-destination 192.168.2.4
### End DMZ .. Add other rules ###
Where,

-i eth1 : Wan network interface
-d 202.54.1.1 : Wan public IP address
–dport 25 : SMTP Traffic
-j DNAT : DNAT target used set the destination address of the packet with –to-destination
–to-destination 192.168.2.2: Mail server ip address (private IP)
Multi port redirection

You can also use multiport iptables module to matches a set of source or destination ports. Up to 15 ports can be specified. For example, route incoming HTTP (port 80 ) and HTTPS ( port 443) traffic to WAN server load balancer IP 192.168.2.3:

iptables -t nat -A PREROUTING -p tcp -i eth1 -d 202.54.1.1 -m multiport –dport 80,443 -j DNAT –to-destination 192.168.2.3
Pitfalls

Above design has few pitfalls:

Single point of failure – The firewall becomes a single point of failure for the network.
Hardware – The firewall Host must be able to handle all of the traffic going to the DMZ as well as the internal network.
Linux / BSD Firewall Distros

If you find above discussion little hard to digest, I suggest getting a Linux / BSD distribution which aims to provide a simple-to-manage firewall appliance based on PC hardware to setup DMZ and gateways:

IPCop
Shorewall
PfSense (FreeBSD based)

DNS Query Denied

DNS Query Denied
James F. Carter
2008-03-20

Symptom:

The DNS server for a domain is upgraded and starts logging errors similar to this:

Mar 20 13:06:11 dns1.example.com named[3357]: client 128.97.12.3#53: query (cache) ‘other.example.net/A/IN’ denied

Workstations which rely on this server as a forwarder, particularly Windows boxes, are not getting recursive DNS answers from it. The users, unable to view their favorite websites, are gathering outside your door with pitchforks. (more…)
