In a nutshell, no you can't. Unless your ISP can bond a pair of connections to a single IP, or load balance incoming traffic over two IPs. Or if you want to do round-robin DNS load balancing (bad idea) so some incoming requests hit one IP, some hit the other. Or if you get your own AS and talk BGP with your providers. But you can't take requests in to one IP and send the reply out from another (think about state). A good ISP won't let you send traffic over their network from an IP they didn't assign you, so you can't spoof the from-address of the reply. So unless you're willing to do some heavy lifting on network configuration, no. Instead of mucking about with this, you're better off buying a decent VPS or dedicated server somewhere with a real network connection. -HKS
