I am currently faced with a situation where i would like to deploy a proxy server on amazon EC2 running on Ubuntu.
What i am trying to achieve is to have Wifi users in each site have their traffic filtered by this Server. On the proxy server itself i would be simply blacklisting all URLs with the exception of 2 specific URLs.
This proxy server is to serve requests from about 7 of such sites
My Network Diagram for each site is as below :
INTERNET <- VPN ROUTER <- WIFI Network ( 192.168.9.0/24) - Wifi Clients <- Private Network ( 192.168.10.0/24)
I have implemented squid proxy servers before however the way I used to implement them is like so :
Private Network -> Proxy Server -> Firewall -> Internet
However due to some budget constraints and the temporary nature of this setup i don't plan to deploy a proxy server in each of the sites.
Just a bit of background info, the Wi-fi router is just a basic home / office router that has pretty limited functionality and the VPN router is pretty standard off the shelf with limited features.
I am just not sure if my approach is going to work, I would like to hear if my plan is actually workable or any other alternatives (low cost) of how i can achieve this.
