I ran the system-config-network about a year ago to set this up. I don't have any real records of what I did, but for example, /etc/ppp/chap-secret has comment lines in it that say: ####### redhat-config-network will overwrite this part!!! (begin) ########## followed by a line wiht my account and password. And of course there is /etc/sysconfig/network-scripts/ifcfg-ppp0 set up as well. Perhaps I did run an adsl-setup script. That sounds kind of right. I am running IPv6 as well and have static internal routes running for IPv4 and IPv6. I run shorewall for IPv4 protection and ip6tables for IPv6. > 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.
