From LAN to ADSL

[miraceti]

Hi, I used to use my computer connected to LAN. Everything was fine but I don't have LAN anymore. Instead, I am going to be connected via ADSL. The question is, what I should configure in order the network will run.

Originally, I had a fixed IP on LAN (no DHCP). With ADSL, I should have dynamic IP (got from DHCP).

I am a bit confused. With ADSL modem, I obtained also a manual for RedHat 8.0. It says that I should only click to change a network option from the static IP address to DHCP and it will run. However, it is not so easy (complicated? ) in Gentoo. There is a description on http://www.gentoo.org/doc/en/handbook/handbook-x86.xml?part=1&chap=3#doc_chap2
but it talks about "adsl-setup", "adsl-start" and "rp-pppoe". I don't know (I am not sitting at that computer right now) if I have installed these tools (probably I haven't and it could be difficult to do it without net) and I have no idea what will happen when I use them in fully working system. Are these option necessary?

I would like to get a simple answer for this question: What should I change in configuration in order to make ADSL working. The best solution would be without installing any software package.

(I still have a live CD with Gentoo since I installed the system, but it is quite old nowadays. I will use the added ADSL modem over the same network adapter eth0 which I used for a connection to LAN before.)

Roaring Penguin (rp-pppoe), 'adsl-start' and 'adsl-setup' are usually only needed for internal DSL modems, or ADSL modems without DNS server.
Most ADSL modems are firewall DNS servers. When you connect to the modem via the ethernet, you need to tell the devise what you are connecting to.

In the file below (/etc/conf.d/net) you change it so it only reads 'iface' for the 'dhcp'. Everything else can be commented out, except what you may need for aliasing, etc.

You then need to make sure 'net.eth0' is started at boot using the following command 'rc-update add net.eth0 default'.
