Re: iptables

Thank you for lot of reply
Wan protocole is IPoA. So I think I can keep eth0 ?
On my debian server, I have dhcp server (isc-dhcp-server), asterisk, apache, samba.
On my windows server, I have ftp server,, sam broadcaster...
I will try to route as you explain to me, and I will tell you later.
Thank you again

Since it's a dsl maybe the interface is ppp0 ? Check if this interface comes up when you dial in.

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.

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  with iptables ?
thank you for your help !


Check if is default gateway for all devices in LAN.

In Debian Server, traffic to Internet must be nated:

iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
