I am using a frame rely connection for Internet.We are using Ms Proxy server 2.0 for internet sharing.
Now I am facing serious problem,all or employeer using ICQ for chatiing in Office times.So I have to block that site.I haqve blocked that site in the web proxy,but now others can't acces that server but they can chat.So Please tell me how to block the chatting service in MS Proxy server 2.0
You can block ICQ access by simply blocking all services to 188.8.131.52, netmask 255.255.255.0... Also, there's apparently a program out there that tunnels ICQ over HTTP. To block access to this, you must block access to www.icqproxy.com, IP 184.108.40.206. ICQ will use UDP port 4000 also.
Hi, I think there is a more powerful version of ICQ available in the Internet. It's a chinese version of ICQ called OICQ. It allows a person to have multiple identities in different dialog boxes all opened simultaneously. Of coz, multiple file transfers and simultaneous chatting is possible. Please tell me how to block this.
