Question by jmack2k5: How to access blocked websites without a proxy? Will reward anyone that helps me get in!!?

I have a bet here at work (with the IT guys) to bypass our firewall and access blocked websites. I can use any method and not get in trouble for it. All they would tell me is that we use a cisco 501 firewall and a proxy servers will not work. We are on a t1 connection and use OPEN DNS. I am more than happy to reward whoever helps me with on paypal

It depends how locked down the network is.

Goto start->run and execute “cmd.exe”

type the command “telnet mail.google.com 110″ (without the quotes)

If the window goes blank then you are able to open a port to the outside world and would be able to run VPN through it.

This can be tricky to setup, however there are paid services that will help. A google search turned up http://www.bananahosting.com/vpn-service-accounts.htm which looked reasonable.

If this doesn’t work, let me know and I’ll try and get more info about your network configuration.

(If you are able to successfully do the telnet test but can’t setup a vpn, let me know and I’ll run a proxy on one of my servers for you on port 110)

    The Cisco firewall is a layer 3 device and not blocking websites based on content. It can only block by explicitly denying traffic to IP addresses of blocked sites over port 80. You would need a packet capture on your machine, and also determine if you are using an explicit proxy (i.e. browser is configured to go to an internal address), this all makes a difference and your course of action depends on these. You can use the packet capture to determine if the HTTP responses are coming from a proxy or the actual site (unless it’s transparent).

    The filtering may even not be done in house. So you need to gather information, install wireshark and nmap and start probing devices up stream. look for alternate paths out your network then change your default gateway if needed.

    The lesson is dont make bets when you don’t have a clue what your doing. Ultimately you need to determine what device is doing the URL filtering.
