This seems to be a grey area.

http://www.draytek.co.uk/products/vigor3300vplus.html - on this page under the WAN Ports section, there is a picture of four internet connections of 512kbps aggregating to become one 2mbps line. This is what I'm trying to achieve (using multiple WAN ports to increase download/upload speeds), but I can't see anywhere that it can actually do this. I know it should say because on some other routers Draytek confirm this.

So basically I just need an owner of the 3300v+ to come forward and confirm whether it can or can't do this.

Thanks in advance,
Brendan
