I don't think you'll be able to split the traffic on that cheap ADSL modem, but I do think that it supports half-bridge mode (aka PPPoE Relaying / PPPoE Passthrough), which would allow you to dial an account from your PC while another (default) account is being dialed by the router.
Unfortunately you'll have to know the IP addresses of Astraweb before you can be able to split the traffic.
Here's a list of the IP addresses for Astraweb that I've just collected by doing a few a few DNS lookups:
news.astraweb.com / us.news.astraweb.com / ssl-us.astraweb.com / ssl.astraweb.com:
207.246.207.*
216.151.153.*
eu.news.astraweb.com / ssl-eu.astraweb.com:
91.208.207.*
193.202.122.*
You can use my Traffic Splitter application (see the link in my signature) with the following route list:
# news.astraweb.com / us.news.astraweb.com / ssl-us.astraweb.com / ssl.astraweb.com
207.246.207.0,255.255.255.0
216.151.153.0,255.255.255.0
# eu.news.astraweb.com / ssl-eu.astraweb.com
91.208.207.0,255.255.255.0
193.202.122.0,255.255.255.0
I'm guessing that the primary Internet account will be your capped account, which will be on the router?
If that's the case, then you'll have to create and dial the uncapped account from yourPC.
Now in my TS application, you'll have to edit like the Auxilary route list and paste that route list in the text file that I've given above. Then you save the file and then you click the Import Routes' All button.
Now you select your Local Area Network interface for the International / Default network connection in Traffic Splitter, so that the default Internet connection will be your capped account.
Next, select your Uncapped PPPoE connection for the Auxilary network connection, so that JUST the Astraweb connections will be routed via it.
I would suggest that you also select the 'Automatically set up routes on the connected interfaces' and 'Automatically (re)connect' options, and then press Save Settings.
Now just press the 'Set up Routes' button and then the traffic will be split accordingly. Next time you run the application, you won't even need to press the 'Set up Routes' button
I would suggest that you run a few trace routes before downloading like crazy from Astraweb. You're more than welcome to paste the trace route results here if you don't know how to interpret them.
For this, open Command Prompt and run the following commands:
Code:
tracert -h 3 www.mybroadband.co.za
tracert -h 3 www.yahoo.com
tracert -h 3 news.astraweb.com
tracert -h 3 us.news.astraweb.com
tracert -h 3 ssl-us.news.astraweb.com
tracert -h 3 ssl.astraweb.com
tracert -h 3 eu.news.astraweb.com
tracert -h 3 ssl-eu.astraweb.com
Those results should be fairly simple to interpret.
The Astraweb trace routes should hop differently from that of yahoo & google. The Astraweb ones will directly hop onto the uncapped account in this case, where as the yahoo & google ones would first hop to your ADSL modem and then onto the capped account.
If it doesn't hop like that, then there's something wrong with the way you setup the routes.
