Hi,

UltraSurf is a hard one to block from ISA itself because it uses the local host computer through port 9666 as it’s proxy to intercept browser requests and encrypt them through 443/SSL traffic through your corporate proxy server. UltraSurf uses a network of anonymous proxies like Botnets that can change dynamically at any given time.

So how can you successfully block it? Well I don’t know if you can totally but you may be able to deter it a bit.
A few ways are:

Policy – Do you have an acceptable use policy in-place? If you do then I would think the threat of job loss and termination should be a darn good deterrent.

At the local host – Using group policy, restrict access to the local host site in IE. That would be 127.0.0.1 and Ultra1 that it resolves to. If you have the capability, restrict TCP port 9666 on the local host outbound. Setting software restriction in group policy is another to prevent the UltraSoft application from running.

On the ISA – Go to http://www.isaserver.bm and download Steve’s blocking anonymous domain sets and configure a deny access rule to help block anonymous proxy access. You won’t totally stop access but the list will defiantly put a damper on accessing the most popular sites.

Collective software ClearTunnel is another ISA add-on to help uncover scrupulous activity.

I can't go internet by using ultrasurf 15.2


Hai Akira, what do you need for the ultrasurf by the way, as i know the app its for proxy bypass for the network server. so it could access sites that are blocked by the network admin.
for the problem it self, you cannot surf the internet because the application has been block by the server admin or the application it self cannot route the internet connection. I suggest to you to uninstall the application if you dont needed and dont know how to use, so you can go surfing the internet again.
So if you want to surf & browse more light i suggest use UC Browser or the opera browser. hope that help
