Re: iptables

You DHCP server must tell your clients which one is the gateway (your debian6 machine must be it)
You will also need a DNS server and make your dhcp inform this to clients as well.

have you done NAT rules? You will need a MASQUERADE one.

Hello,
I'm French, I'm sorry for my bad english.
I'm a beginner debian user.
In my home network, I have a linux machine with debian6.
My debian has to do dhcp server with isc-server.
I have 2 network card, eth0 = public Ip (adsl modem)
eth1 = lan.
My dhcp server runs.
But I can't connect to internet with pc's.
Description :
 
network  : 10.20.30.0
mask : 255.255.255.0
Windows server: 10.20.30.2
Linux server (Debian6) : 10.20.30.1 (DHCP a    nd gateway to wan)
Accesspoint Wifi : 10.20.30.3
NAS server : 10.20.30.4
MAO PC: 10.20.30.5
laptop : 10.20.30.6
IP phone : 10.20.30.7, 10.20.30.8, 10.20.30.9
I can connect to lan machines but not to wan.
 
cat /proc/sys/net/ipv4/ip_forward is 1
 
What are routes I have to create with route command ?
How can I routed 80 port to 10.20.30.1  with iptables ?
thank you for your help !
