Re: [Home Networking] DSL out after EL maintenance - bridge mode You can setup multiple Routers in a bunch of different ways as long as only "one" Router is handing the PPPoE authentication (all router from that point back in toward the PCs will use either DHCP or Static IP assignment depending on the users preferences and skills) however, that makes opening services to the Internet very complicated and sometimes painful because you have to map though extra Routers that a normal home or small office LAN setup would not have. What most people don't know is that all the ZyXEL P660R DSL Modems from Earthlink are Full Routers and are ready support up to 32 PCs in their Default DHCP settings from Earthlink (you simply supply a port duplicator aka a 10/100 Multi-port Switch to create a LAN.) They are called "2 in 1" devices as they contain a DSL Modem (ADSL2+ support in fact) and a Router all in one case.
On some setups that have only Macs on the LAN there are problems with DHCP because the Macs may not all have individual computer names for the Ethernet so it makes keeping them sorted with DHCP fun as some Routers do not like that even though the MAC IDs are different as it looks like multiple requests from a single PC since they are trying to connect with out a computer name.
A fix is seen here (names in both the "DHCP Client ID" field in the Network Prefpane, and the "Computer Name" in the Sharing Prefpane need to match each other exactly) :

The reason behind placing the Earthlink Router/Modem into Bridge Mode is to allow the customers extra purchased Router to handle the PPPoE connection instead which gives it the Public IP address and makes any Port Forwarding much simpler to setup since that prevents Double or Triple NAT/NAPT from being a deterrent to opening any servers to the Internet. By keeping it simple, it makes later setup and other changes much easier to implement.
