technically speaking, two routers with two public IP's, each with half the office behind them each is "load balancing". if you don't want a cheep hack form of load balancing (where connections are handled properly based on line load) talk to your ISP. they're happy to help.
- Making example.com:21 and example.com:80 be separate servers.
(in the cisco world) create an ACL patching each port, and set them on a route-map with the next-hop being the server(s) in question.
Conversely, making example.com:80 and example1.com:80 be one server while example.com:21 and example1.com:21 are another server.
EASY to do with a load balancer. (though many will say it's basically the same thing.)
- Transparent proxies.
already covered in the comments above. your router can easily move flows of TCP port 80 traffic to another destination.
