I am building a CentOS 5 box to ship to Houston which will be a gateway system on an SBC DSL connection for a while until the client gets a T1 installed. I have read up on using adsl-setup and related software, but never done PPPoE on anything but LinkSys commodity boxes. I have examined the adsl-setup script, and I think I understand how this works, but want to be sure I understand things first. The box has dual 10/100/1000 NICs, eth0 for the internal LAN, and eth1 for the PPPoE interface, and later the T1. After running the adsl-setup script, answering the prompts, it appears that it will create an ifcfg-ppp0 interface which will take care of handling the eth1 interface. It also should handle default route setting when the system boots, and do the initial setting of the /etc/resolv.conf file. We will not be using the adsl package firewalling/NAT as we have our own procedures for this. This seems reasonably straightforward, but I know Murphy is always ready to pounce as soon as I assume anything. Is adsl-setup and its associated programs the best way to handle this on a CentOS box? I think that the WAN interface will appear as ppp0 when the system is running. When we move the system to the T1, is it sufficient to edit the ifcfg-ppp0 script setting ONBOOT=no, then do a normal configuration of eth1 using system-config-network? This is something I will have to talk somebody through over the phone unless it would work to connect the DSL modem and T1 router to a network hub/switch with eth1 so that I could configure eth1 while logged in via the DSL connection, the restart the networking to have it bring down the DSL connection, then bring up the T1. What am I forgetting? Thanks. Bill -- INTERNET: bill at celestial.com Bill Campbell; Celestial Software LLC URL: http://www.celestial.com/ PO Box 820; 6641 E.
