Something screwed up in the upload of the attachment. Try again now - I have edited the original post above.
Because it is also a router and firewall and wireless access point and forty other things the config file is absolutely vast with a ton of stuff which is irrelevant for use as a modem but would be used if you turned it back into a wireless router. So it has got settings for more stuff than the parson preached about.
When you are using any PPPoE modem only the router knows about ISP settings such as PPP login usernames and passwords. The modem knows nothing about these.
For our purposes the config file has DSL line type settings in it and these need to be right for you.
But it also still has all the settings that you can set in the GUI, stores everything there is in the case of this modem, so it also stores usernames and passwords, enables features, such as turning on or off http or https web admin access, admin access via telnet and ssh, turns on or off ftp access iirc, and enables SNMP management. The list is still very long even when used as a modem anyway. Unfortunately all the router and wireless related default stuff is still all in there which makes it all very long.
The config is readable text so you will be able to guess what a lot off it means anyway, and I edit mine with a text editor.
My three modems have slightly different config, they have different names and different admin IP addresses for ease of access, which is a nuisance, so I have written a program for the iPad that takes one file and can make customised altered copies of it for modem 2 or 3 just to take the drudgery and errors out of this repetitive process whenever I make a change to the saved base master config for modem 1.
