Internet connection via LAN network.

Hello!
I took a look many HOWTOs but i can not understand how to connect ot the internet via LAN.
I know that have to be done with PPPoE but in all documentation tha i read i have exaples with ttyS0 port or some other serial port.
I use LAN. How to connect to the internet?

Probably i can't understand or i have wrong documentation.
These are the steps that i do:

- connect to the dhcp server. - DONE
- get IP adress on eth0 interface - DONE.
- connect to internet - FAILED.

I have IP, i know the ISP's DNS server and i have to configure the PPP.

How to connect my computer to internet via LAN?

Thanks in advance if anybody help me.
I am very appreciated at any help.

Would you please take the time to post the hardware setup you are trying to get working.

PPPoE for me is looked after in my routers configuration. If you have a dsl modem, you may have to install and configure PPPoE on yoru linux machine.

So. before we can help more, we need to know all the pieces of your network connection.

If you modem/router uses dhcp then eth0 needs to get its ip address via dhcp. i.e. setup your networking to use dhcp. Sorry don't use slack so cannot advise on method.

O.K.
I have only a plain lan. I have no dsl or some other kind of modems. Only a plain lan broadband network.
There is a proxy that i have to access, dhcp that give me IP adress and that is all.
No modems, no dsl, no adsl only a lan cable plugged in to a router from my ISP.

My active network interface is eth0 with dinamically changed IP adress.
I can get a IP now from the dhcp. it is not problem for me.The problem is how to access internet now.

Can you ping a known public ip address? (204.246.1.20) Can you ping a dns address? (www.yahoo.com)

do route -n

is there an entry with a UG next to it? That would be the default gateway. Is it present and correct for your lan?

Also do a cat /etc/resolv.conf -- this file should contain the IP address of the dns server your machine will use. If this entry does not exist, or of the UG entry in route -n display is wrong or non-present, then try manually adding the dns and gateway values. If it still does not work, then there is something wrong with basic ip connectivity.
