There R two thing to consider:
1. Load blalancing users from your network to the internet
2. load balancing traffic going towards your servers from the internet
IIRC, LinkSys is doing only the first.
For loadbalancing your servers you will need to run bgp or to use
tools like "Linkprof" from www.radware.com (I use this tool and I am
very happy with it. I use 3 ISP with 4 links and 4 public address
ranges)
How does it work: Simple NAT.
1. For loadblalancig your users surfing the net, some connection will
use ISP1 public address for NAT/PAT other users will use ISP2 NAT/PAT.
2. For loadbalancing you servers, "Linkproff" is DNS server which will
do roundrobin loadblalancing, each time returning diffrent ISP public
address.
Same thing can be done with Linux/BSD but some custom scripting is needed
