I'm wondering if anyone has managed to figure out a way to have an Amazon EC2 instance behind a VPC work with multiple public IP addresses? The issue is with asymmetric routing. It's been resolved in the Linux world (http://blog.bluemalkin.net/multiple-ips-and-enis-on-ec2-in-a-vpc/), but I can't seem to get it working under FreeBSD. Using the setfib command, I'm able to manually go out through either interface, but for incoming packets to a webserver that listens to both interfaces, no dice. :( Patrick
