route nettverk fra eth0 til eth1

[danielsn]

Har søkt litt på nettet nå, men finner egentlig ikke så mye.. Noen som har en enkel guide på å route nettverk fra eth0 til eth1?

Les om iptables og forwarding, så finner du det du leter etter. man iptables i konsollen.

Beklager at jeg ikke fant noe lettere, men det funker flott hvis du orker å sette deg litt inn i enten iptables eller bridging.

Eller en enklere måte:

 

Hello,

 

The following will explain how to share your Internet connection:

 

Note: Type all the following commands in a root terminal, DO NOT use sudo.

 

1. Start by configuring the network card that interfaces to the other computers on you network:

 

# ifconfig ethX ip

 

where ethX is the network card and ip is your desired server ip address (Usually 192.168.0.1 is used)

 

2. Then configure the NAT as follows:

 

# iptables -t nat -A POSTROUTING -o ethX -j MASQUERADE

 

where ethX is the network card that the Internet is coming from

 

# echo 1 > /proc/sys/net/ipv4/ip_forward

 

3. Install dnsmasq and ipmasq using apt-get:

 

# apt-get install dnsmasq ipmasq

 

4. Restart dnsmasq:

 

# /etc/init.d/dnsmasq restart

 

5. Reconfigure ipmasq to start after networking has been started:

 

# dpkg-reconfigure ipmasq

 

6. Repeat steps 1 and 2.

 

7. Add the line "net.ipv4.ip_forward = 1" to /etc/sysctl.conf

 

# gedit /etc/sysctl.conf

 

8. Reboot. (Optional)
