Netspace Business Plan using DLink DSL-302G modem

These instructions are based on using a Linux box as the internet gateway (router) and firewall and assumes that the DSL-302G modem is in its default configuration. Netspace Business Plan appears to be a Telstra product resold by Netspace. It has a static IP address and uses ethernet bridging (RFC1483). The DLink DSL-302G modem is a fairly new product that has a large range of features, including both USB and ethernet ports. It is also cheaper than others in the DLink range (we currently sell it for $195 inc GST), and as Netspace wants to charge $450 for an ADSL modem there are considerable savings to be had if you supply your own.

1. Set up the ethernet port connected to the modem to receive an IP address via DHCP. It will be in the 10.1.1.x range.

2. Point a web browser to http://10.1.1.1 which is the address for the modem's configuration page. If you are running something like IPCop then you can easily connect via another machine if you set IPCop to serve up IP addresses on the internal network (DHCP), and turn off the web proxy cache. The IP address of the network card interfaced to the internal network should be in a different subnet to 10.1.1.x.

3. Delete the default PPP configuration by navigating to WAN - PPP and clicking on the trashcan, then OK. Click on 'Submit' to continue.

4. Change the ATM VC settings at Bridging - ATM VCC. Click on the pencil and change MUX type to LLC. (VPI should read 8, VCI should read 35.) Click on 'Submit'.

5. Now set up the ethernet bridging option by navigating to WAN - EOA. Click on 'Add', then 'Submit' (the default options are fine).

6. Disable NAT at WAN - NAT. Select the 'Disable' radio button and then click on 'Submit'.

7. Now set up bridging between the WAN and local interfaces. Go to Bridging - Bridging, select interface eoa-0 and click 'Add'.

8. IMPORTANT: The changes must be saved, then the modem rebooted to effect the changes. If you don't do this nothing happens. Navigate to Admin - Save & Reboot. Click on 'Save' and then click on 'Reboot'.

9. Once the modem has rebooted you can then change the IP address on the ethernet port attached to the modem. It needs to be set to the end-user IP address supplied by Netspace. The gateway IP address and DNS server IP addresses are also supplied by Netspace and will need to be set manually. Test that it is working by pinging the gateway IP address.

If you need to reset the modem to its default configuration (and start again), you can go to Admin - Save & Reboot, choose 'Reboot from Default Configuration' and click on 'Reboot'.


Bigpond ADSL using IPCop and Alacatel SpeedTouch modem

Bigpond offer discounted ADSL if you are preselected for Telstra local and long distance calls.

1. Set up IPCop so that the ethernet port attached to the modem is set to obtain an IP address via DHCP. (On the installation I did, the IP address is 10.0.0.1)

2. Point your web browser at the IPCop box and go to 'Dial-up'. Add a new profile by typing in a profile name (eg Telstra Bigpond).

3. Under telephony, select 'PPPoE' for the interface, set the idle time-out to 0, tick the boxes marked 'Permanent connection' and 'Connect on IPCop restart' and set 'Maximum retries' as high as you like.

4. Under authentication, type in your username (which is of the form user@bigpond) and password. Method should be 'PAP or CHAP'. Save the profile.

5. Go to 'Home' and click on 'Connect'.

iiNet Bliink Biz using DLink DSL-300+ modem

iiNet has a range of business plans which include a static IP address and differing levels of speeds and download quotas. They use PPPoE. For a fee of $199 they will supply a DLink DSL-300+ modem and an ADSL line filter, which is very good value. The included DLink DSL-300+ modem has firmware especially configured for iiNet by DLink.

1. Set up the ethernet port connected to the modem to receive an IP address via DHCP. It will be in the 192.168.0.x range, which is rather annoying as many simple networks use this IP address range.

2. Point a web browser to http://192.168.0.1 which is the address for the modem's configuration page. If you are running something like IPCop then you can easily connect via another machine if you set IPCop to serve up IP addresses on the internal network (DHCP), and turn off the web proxy cache. The IP address of the network card interfaced to the internal network should be in a different subnet to 192.168.0.x.

3. At the account configuration page, simply enter your iiNet username (which must have @iinet.net.au in it) and password. The defaults of PPPoE connection, pap authentication, connect on demand enabled and 0 idle time are all correct.

4. Click on 'OK', then choose 'Save changes to Flash now' and click on 'OK'.

5. The modem will reboot. Click on 'Connect'. You should see 'Connected' and the IP address will change to your allocated address.

6. The ethernet port attached to the modem should now change to your allocated IP address and you are away.


Netspace Home ADSL using DLink DSL-302G modem

Netspace home plans start from a quite reasonable $49.95 per month for 1G of data at 256/64. For $69.95 a month you get a 512/128 connection with 6G of data. Netspace has a range of addresses and servers that are free as far as data usage is concerned, which makes these plans more attractive. They use a dynamic IP address and connect using PPPoE with an MUX type of LLC.

1. Set up the ethernet port connected to the modem to receive an IP address via DHCP. It will be in the 10.1.1.x range.

2. Point a web browser to http://10.1.1.1 which is the address for the modem's configuration page.

3. Fill in the PPPoE username and password. Your username must include the @netspace.net.au

4. Change the ATM VC settings at Bridging - ATM VCC. Click on the pencil and change MUX type to LLC. (VPI should read 8, VCI should read 35.) Click on 'Submit'.

5. Navigate to Admin - Save and Reboot. Click on 'Save', and then click on 'Reboot'.

6. After the modem reboots, click on 'Connect'.

7. Now, change the interface connected to the modem to a static IP address (the same as was allocated earlier), filling in the gateway and DNS settings as advised by Netspace. The modem does Network Address Translation for you from this interface to the gateway given by Netspace.
