I saw your message on the NET : I included it below. I have similar problems
with my DLS 300G+ enm my Netgear router WGR614.
I accessed internet without problems directly trough my D-link modem. With
the Netgear now attached I can.t access internet through my outer/modem. I
cannot even reach my modem. 

Did you get an answer / solution in the end. Can you please share that with
me.

Thanks

I have 2 Mandrake 8.2 boxes and an XP Pro box connected to a Netgear

RP114 router/switch but can't get the router to receive it's IP from the

modem via the router's WAN port. The internal IPs in the Flash memory of

the 2 devices are:

Netgear RP114 router/switch: 192.168.0.2 (reset from 0.1)

D-Link DSL-300G+ ethernet modem: 192.168.0.1

The first issue I need some authoritative advice on is PPPoA/PPPoE. My

ISP, PlusNet, uses PPPoA and issues IPs as server-assigned/dynamic.

However, the resulting IP is actually static, so it may be that I have

static and dynamic config options, to further complicate matters :-(

The modem connects to the router via ethernet and is configured:

Connection Type: PPPoA

Encapsulation: VC Mux

Username: myusername

Password: mypassword

Authentication: CHAP

Connect on demand: Enabled

Idle time: 0

PlusNet confirmed these settings are correct.

To configure and test the modem I had to by-pass the router and connect

it directly to the XP machine with DHCP client settings enabled on the

XP machine. This worked fine:

IP Address: 212.159.45.120 (from connection results)

Gateway: 212.159.45.121 (from connection results)

... so the modem works and PlusNet's help ends there :-(

When I plugged the modem into the WAN port on the Netgear RP114

router/switch my problems began. As I intended to eventually have 3

machines connected via NAT I re-set the XP box to:

IP: 192.168.0.4

Subnet Mask: 255.255.255.0

Default Gateway: 192.168.0.2 (router's LAN IP)

The Netgear router has the following Encapsulation menu:

Ethernet

PPPoE

PPTP

When I noticed PPPoA wasn't listed I assumed the router was incompatile

with a connection based on PPPoA but some sources have told me that the

PPPoA is only relevant between the modem and the ISP, in which case the

router doesn't need PPPoA. Is this true?

If the router does need PPPoA I'll simply have to exchange it. Assuming

it doesn't need PPPoA, my next dilemma is whether to set it to PPPoE or

Ethernet. Again conflicting opinions.

If I set the router to PPPoE the settings specify:

Encapsulation: PPPoE

Service Name (left blank)

Usnername: myusername

Password; mypassword

Idle timeout: 300secs

There are then options for an ISP-assigned or static IP. Why are login

details required if the modem has already taken care of this? Whatever I

enter makes no difference as the SYSTEM INFO shows the WAN IP to be

0.0.0.0, subnet: 0.0.0.0.

Since I am using NAT I have disabled the router's DHCP server

capability. Am I correct in assuming that NAT only requires a

NAT-capable router and static internal LAN IPs on the client machines?

If there's more to it maybe this is why I cannot connect.

As a last resort I switched the router settings to Ethernet and assigned

the IP manually:

WAN IP Address Assignment

------------------------

Get automatically from ISP (default/unchecked)

Use fixed IP address: (checked)

 - IP address: 212.159.45.120

 - IP Subnet Mask: 255.255.255.0

 - Gateway IP address: 212.159.45.121

This finally resulted in the WAN port getting the correct IP but the

internet connection still failed.

I've had a over week of this and it's driving me crazy. Can anyone help?
