Proxy Bypass Websites

[cyberforester]

Just recently I learned about the huge number of websites that offer users the ability to foil proxy servers and content filters. How are these handled by Wingate?

make policies in ban list & advanced tab for the following: (this is the most common bypass sites i have discovered so far)

Cloya
Bofio
Ulira
Ebovo
Prapy
Ewov
Eyop
Eruj
Uvoy
wujie
glype
ultrasurf
ultrasearch

in www proxy service:
ban them by "sites containing Cloya" as an example.

if u r paranoid like me, in advance tab create a policy with criterion "Not HTTP query strings contains Cloya"... "ultrasurf"... "by-pass" or "bypass"

be sure to create them in separate criterions, ex:

Filter1
"Not HTTP query strings contains Cloya"

Filter2
"Not HTTP query strings contains Bofio"

and so on...

Filter1
"Not HTTP query strings contains Cloya"

Filter2
"Not HTTP query strings contains Bofio"

Actually need to be careful about combining logic like this.

WinGate uses logic of filter1 OR filter2.

In this case, either "not query string contains Cloya" or "not querystring contains Bofio".

this will let anything through except if the query string contains both Cloya and Bofio (unlikely), so it will let everything through.

from boolean logic, NOT A OR NOT B = NOT (A AND B)

If you combine criteria in the same filter, then you would have

Filter1
"Not HTTP query strings contains Cloya"
"Not HTTP query strings contains Bofio"

which logically then is "Not HTTP query strings contains Cloya" AND "Not HTTP query strings contains Bofio" - e.g. neither contains Cloya nor Bofio, which is what you want.

Actually putting both of these in the banlist will have the same effect, so putting them in the Advanced tab is probably unnecessary in this case.

yes my apologies. my setup is like this, not the one with two filters

Filter1
"Not HTTP query strings contains Cloya"
"Not HTTP query strings contains Bofio"

yes putting those in banlist tab will serve the purpose of banning sites containing cloya /bofio. but my purpose of placing them in advanced tab, because there are sites, blogs and individuals that supports cloya / bofio, in w/c even in their website (URL) dosent contain such cloya or bofio. its juz an extra precaution, i hope u got what i mean.

I see - because you can't check QueryString from the banlist.

Maybe I should allow that...
