I am trying to move my servers over to AWS but am having trouble getting my metadata requests right. My site makes constant meta data requests to several popular video sites on behalf of the users. Because of this, I must use a lot of IPv4s.
Everything works fine without any load but once I start sending traffic to the new instance, within 5 minutes it is no longer able to make the meta data requests successfully. I believe this has something to do with the way the private IPs are routed as this is a very different setup than usual.
