I have a small project that I need done and I don't have time to deal with this myself (I also need this quickly), so help is needed.
I need to set up virtual firewall/utm that forces (transparent) proxy use on the traffic passing through it and I need stats about the traffic. ... It's up to you what software you would like to use to accomplish this, I was thinking some free virtual firewall or utm distro, but if you have better options in mind, I'd like to hear about it. ... We also need some ports forwarded from public ip(s) to internal network in case of NAT.
2. Proxy is already set up, firewall should send all traffic destined to internet (*, port 80) to proxy server (currently running on dedicated vm, public ip, port 8118).
