I recenctly setup a VPN Lite network for my bro's gf between her office and another office. I also setup myself up as a location for testing purposes.

All sites also need to be connected to the internet and so according to the VPN Lite installation notes you require a router that has the ability to have share a connection. Each connection had it's on user name and password. Originally I only used my VPNLite username and password for the second connection.

But then it struck me, you could possibly be connected to two different internet accounts at once... Further more one account could be used for international and the other for local.

So currently I have my international cap account and one that has been capped already (still has 10GB local available).

From my limited TCP/IP knowledge I assume the only thing I need to get right now is the static routing so that local data is routed through the local cap connection and international data is routed through the international cap.

Is this simple, are there a fixed range of local IPs that would make using static routes practical?

I can't imagine the intl. cap I'd save if I could get this to work, my adsl would last longer without having to purchase top ups.

I read somewhere that the connections share the available bandwidth, quite obvious, so if you have a 4Mbps line the max the two connections can use simultaneously is is 4Mbps.

Further more I'm not sure how many simultaneous connections you could make but what if you additionally bought a unshaped cap for online gaming and set the static routes just for WoW for e.g. you would save a lot of that unshaped cap...

Is this possible or am I dreaming?

Thanks ponder! Not sure yet how to implement on my Mega 200 but I'll go through those threads.

Dope and here I thought I was coming with something new and everyone has been merrily using the concept for yonks :/

No problem. I know nothing of the Mega 200 but I suspect it won't be posible with that device.

What you could do is put the Mega 200 into bridged mode. Connect a PC to it that acts as a router handling all the PPPoE sessions, firewalling, dns etc and then have the LAN connect to that PC via a second ethernet interface. You don't need a super duper new PC to do this either, a PIII should be fine. Look at the IPcop & Ubuntu threads.
 
Great suggestion but I like having it setup on the router.... less hassle :/

I've got the two connections... connected. Tried to add one static route to test one website to see if the concept would work but can't ping not getting any through put until that route is deleted and it goes back onto the default internet connection.

Any one got any clues? Or will this not work on the Mega 200? I think the Billion 800 firmware can also be loaded on these units does that have perhaps bare better compatibility with the concept?

I just scanned through the manual and it states that the router can only have one WAN IP address with PPPoE (Chap 4, Pg51). This will prevent you from connecting to two accounts as far as a I can tell. The router allows you to setup up to 8 WAN links but it looks like you can only use one at a time.

These devices (software) are usually not made in mind with using two simultanious connections.

No idea about the BIllion 800 firmware as I could not find such a model listed on the billion site.

Thanks for taking the time to lookup that info...

I've uploaded a screen shot of the status of the connections

http://www.goldbull.co.za/adsl shared connection.jpg

Each connection uses a different Telkom Internet account and has it's own IP address, from what I can see at least.

Would I be correct in assuming I just need to setup the few hundred static routes in order to get it to work?
 
See if you can establish another wan connection to a different ISP, get a local 1GB prepaid or something for testing. You should have dual gateways then if it works but I don't see how. You can test with a few local routes.

VPN is not exactly the same as another ISP connection but what the hell, try it.
If it was as simple as this then people would not be using the methods in those other links I posted.
 
I've had VPN and Telkom Internet working simultaneously.

Ok... just tried two different ISPs and both connect. In the static routes you can select which of the interfaces to you use for the route, the "intl" account is called ipwan and the "local" account is called "ipwanVPNlite" but has the other ISPs user and pass in.

As a test a try it with www.mygoodies.co.za IP addy: 196.40.106.216 before adding a static route i test that I can ping and the tracert shows the route as going on the "intl" cap.

Then I try add my route, I assume I must use: 196.40.96.0/20 with mask of 255.255.240.0 (I'm not 100% sure on this side...)

Immediately after adding the route I try ping/tracert.... And nothing :D request timed out is all I get...

I'm passing on the logic from using Telkom Internet and VPNLite simultaneously... It must be the routing or another incompatibility on the other WAN connection that it won't work...

Any other ideas?

Yes, you could probably run many more VPNs as well but you have to keep in mind that a VPN runs "over" or "on top" of your existing internet(ipwan) connection. They are not the same thing as you need internet access to establish a VPN connection.

In order to support dual wan links your wan interface on the router would probably need to have features like sub interfacing or multiple dialer interfaces which you are only going to see on pricier Cisco models.

I suspect you still only have one default gateway? (Previous screen you posted)

VPNLite is a Telkom product you can use it without any Internet connection at all. You set it up as a normal WAN link with its on Username and Password, as you would with a Telkom, or what ever, Internet account. It uses Telkom infrastructure and does not move through the internet at all. Perhaps this will explain the technology a bit better: http://www.telkom.co.za/products_services/vpnlite/faq.html

From that you'll see it's pretty much like connecting to any other ADSL ISP. You have a monthly cap etc etc etc

I believe the router must use sub interfacing as when you set up the static routes it asks which interface the route applies to i.e. wanip connection or wanipVPNLite connection. Bare in mind I've changed the username and password for wanipVPNLite connection to my secondary ISP details.

So I would have to disagree with your earlier statements regarding my VPN connection running "on top" my internet connection. I can run one or the other or both at the same time, completely separate entities.

I only find out about this tech recently and was quite amazed at how well it works...
 
Then I give up. Would be nice if I had one of those routers to play with.
 
This VPN-lite just looks like a IP-VPN on the telkom infrastructure, has nothing to do with an internet connection.

yip supasta... it would seems it's exactly that...

any ideas on how to setup the router with two accounts and route all the local traffic to one of the accounts?
