A firewall and a proxy server both provide network security but work in different ways. Hackers will often hide their identities while attempting to gain unauthorized access to vulnerable servers.

OK, I wanna set up a firewall/proxy server for use on my personal network. I say personal because I'm already wired to my school's netork and I'm sick of getting hacked, ping bombed, etc etc ...

In the case of a proxy (or ALG), however, the HTTP proxy performs specific checks on the requests it allows through, so that many attacks on the server may fail to get through the firewall at all.

At work all web access goes through a proxy server, and all useful ports are blocked by a firewall. I'd like to find out if there is any way for me to access and edit files on my web server from work.

If you use a free proxy service at work to evade your firewall filters, you may be putting yourself and your company at risk.

Escaping the firewall with an SSH tunnel, SOCKS proxy, and PuTTY If you want to escape your network's filters and censorship, or simply surf safely, SSH tunneling is the best solution.

Reverse proxy startup ngrok Inc. today debuted a GSLB, or global server load balancing, tool that promises to speed up application response times and reduce the risk of outages.
