Only port 80 is open from the outside. My question is, what if someone compromised the box in any way, I want to deny them access to our local lan. However, just thinking about this, if someone got in through SSH or something they could just disable iptables, no?

I was thinking of denying traffic from the proxy to our LAN but is that irrelevant? I still need my LAN to talk to the proxy server since our back-end webservers need to communicate w/ this proxy server.
