Re: iptables

Hi,
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.

      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 !
       



    Manu:

    Check if 10.20.30.1 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
