Proxy and Tunneling at JTAN

Direct Web Proxy Access

You can access the JTAN proxy services only if you have direct access to the JTAN network. If you have a dedicated host at JTAN, you can use the proxy directly. If you connect to JTAN through another ISP, or dial-up, you need to tunnel first before you can use the proxy.

So, assuming you are on the JTAN network, either directly or through a tunnel, you can use the WWW proxy by telling your browsers to use a proxy rather than trying to connect directly. Our proxy is at the address "webproxy.jtan.com" on certain ports.

Anonymizing (Privoxy) Mode:	port 3128
Transparent (Squid) Mode:	port 3129

The anonymizing proxy on 3128 is effectively the Privoxy anonymizer/filter set to "medium" mode. This will strip some revealing headers from your requests, stop some cookies, but it will not hide the type of browser you are using. For maximum protection, combine use of our Privoxy filter with local "private browsing" setups, privacy and adblocker plug-ins on your PC. Some The transparent proxy on 3129 is effectively a Squid Cache. It will let everything through, including cookies, but it will obscure your IP address, letting you surf as part of the JTAN crowd. Both proxies provide caching. Privoxy redirects through Squid, so the cache is shared.

Bottom Line: If you want to protect your identity and shield yourself from many advertisements, use 3128; if you want maximum compatibility, use 3129. Note that many sites use cookies. Sites like PayPal and eBay may force you to use transparent mode. When tunneling to access our proxies, you need to be careful about configuring your browser. If you are using a tunnel to webproxy.jtan.com" on port 3128 then you need to tell your browser to look for the proxy at the entrance to the tunnel. This will typically be localhost on your PC!!

In these instructions we assume you have used a tunnel to connect to our webproxy, and that tunnel is at your localhost port 8080.

How you tell your browser to use a proxy at localhost:8080, exactly, depends on your browser. There are too many browsers (and versions thereof) for us to give you detailed instructions for every possible one. Fortunately, it isn't too hard. You want to find the spot in the browser menus where you configure network options and select the option to use a proxy.

Microsoft Internet Explorer 5.5

Here's an example with Microsoft Internet Explorer 5.5 running on NT4.0

First click on "Internet Options" in the "Tools" menu:

Tools Menu

Then, under the "Connections" tab you will find a button for "LAN Settings...". That's where they hide the Proxy option. Simply enter "webproxy.jtan.com" as the "Address" and 3128 as the "Port".

Opera 6.0

Opera has pretty nice Proxy configuration in the Preferences page under the Network tab. It allows you to specify hosts that you don't want to use the proxy to access. For example, PayPal can sometimes give problems if you try to access it through a proxy. Also, there's really not much sense using the JTAN proxy to access JTAN hosts, so these could also be exceptions.

Here's what the Opera 6.0 Network Preferences dialog looks like on a Linux box:

Another cool feature about Opera Browser (can you tell we like it?) is that you can easily enable and disable proxying and the use of javascript from the "File" menu:

Proxy Tips

You probably want to test the proxy to prove to yourself that you really are disguising yourself. An easy way is to check your IP address. This page will report back your IP. Compare what it says when you are using the proxy to what it say when you aren't. Another good page for testing is the "Shields Up" page at grc.com

For the most part, using the proxy will be totally transparent, but there are sites that will give you problems. Never forget you are using the proxy. What some folks do is to run two browsers. One they use for trusted sites that they want 100% Microsoft compatibility for (MSIE is good for that, for the most part), and the other browser they use only for anonymous browsing through the proxy with cookies and javascript disabled.
