2820 performance question was created by robster
Hi

I am thinking of buying the 2820n and connecting to my BT broadband and an u2 broadband on my 2 BT lines.

Question is this.

If I do a performane test would I see down load speed of 12 Mbs (I get 6 per line) and 512kb upload.

Or would the maximum still be 6 down load but could have 6 on each but diffnt jobs and the same for upload.

My hope and preference would be the combined amounts!

You would get 2 x 6Mb/s - the two connections would have different IP addresses, so a remote server wouldn't know to split the download.

So, two PCs could download at 6Mb/s each at the same time, or one PC could do two downloads at 6Mb/s at the same time, but not 1 x 12Mb/s.

Many thanks for the reply.

Not perfect BUT certainly better than a single 6mb download!

So I guess I connect this device to my BT broadband and the hook my o2 broadband Ethernet connect to the wan Ethernet connector and I am away.

If only it was that simple! :D

Yes sort of ! If you want to make sure that PC1 is using its full allowance of ADSL1 and PC2 is using its full allowance of ADSL2 then you will need to have a look at Load Balaning Policy under the WAN section of the Management GUI. You can do lots of clever things but it is all IP or port based which is not ideal. Take a look at this which explains how to set it up:

and the user manual (Section 3.1.6):

Hope that helps.

Oh

So this is a totally manual process?

I cannot leave it to the Draytek to automatically use the least used WAN?

That is a bit of a bummer!

Also it does not look like I could assign one IP address and tell it to always use one WAN for ALL traffic regardless of IP destination?

Both the above points makes the use of the Draytek pointless for me. :?

UNLESS I have missed something?

I think you can do something to get to to do it automatically but you would need to set the WAN2 ethernet port to work at the actual ADSL2 speed rather than at 100MB or 1GB which would be the ethernet speed.

Never done it that way though.

You can set IP 1 to go via ADSL1 and IP 2 to go via ADSL2. That would be two simple rules:

All IP traffic from 192.168.x.1 use WAN1
All IP traffic from 192.168.x.2 use WAN2

In the Load Balancing Rules most of the items are optional. You can be quite generic as above to simply push traffic out on different ADSL's dependant on internal IP address, and then use fail over in case that ADSL goes down.
