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
