Request to server x Reply from server y
- by klaasio
I need some advice from you guys:
I'm dealing with a custom loadbalancer/software for which we will use 2 main servers and about 8 slave servers. In short: User sends request to main server, main server will receive and handle the requests, sends a request to a slave server and slave server should send data DIRECTLY to the "user".
User - Main server
Main server - Slave server
Slave server - User
The reason for which data should be send directly to the user and not through the main server is because of bandwidth and low budget.
Now I have the following idea's:
-IPinIP, but that is not possible in Layer7 (so far i know there some expensive routers for that)
-IP Spoof, using C/C++ we will make it look like the reply came from main server.
But I was thinking, perhaps the reply "slave server - User" could just come from a different IP without causing issues in the firewall from the user or his anti-virus. I don't know so well about "home" firewalls/routers and/or anti-virus software. I guess the user machine wouldn't handle it well?
