comment In Wireless Networks, What is IV?
It's sent in the clear over the wire, but it does encrypt because it is part of the key. The point is to encrypt each packet with a different key.

comment Ways to estimate which network destination result is shorter/faster network path?
If you definition of "faster" is the time it takes to reply to a custom database request, then time that. That's how you'll know which one is faster. (If you have cooperation with the other end, ask them how to tell. Perhaps they'll even offer you a specific query for that purpose.)

comment Why Place Load-Balancer Behind Firewall?
The web servers are only on the internal network if they're behind a firewall. That's kind of the definition of "internal network". If a device is connected to a load balancer that is connected to the Internet, it's not on an internal network unless the load balancer is also a firewall. (If the load balancer is also a firewall, then it's kind of redundant. Though some people prefer to control everything from one firewall.)

comment Providing internet redundancy for our colocation provider
I would hope the two ports they'd be giving him would be off different switches. Otherwise, it seems they should be able to provide the same level of redundancy in software on their end.

comment Routing doesn't working in linux
How did you establish it's not forwarding packets? Do you have ip_forward set to 1? Is it supposed to be doing NAT? (If so, did you configure NAT?)

comment Reliable way to get external IP address
What is your precise definition of "external IP address"? If you mean the IP address that other sites on the Internet see your web requests as coming from (possibly the address of your HTTP proxy), then you are doing it the right way. If that's not what you mean, then maybe not.

comment Is it possible to rate limit based on host headers? i.e. not just on ip address
@codecompleting The idea is that the server would tell the client if it's placing too much load on the server. If it changes, you tell the client that it has changed. You won't have to update the client library because it will contain fixed logic to respect the rate limits that the server commands.
