Please I need to know hot to block or deny a proxy softwares from Cisco router.
Explaning: I have a network running and I have a proxy server (Microsoft) which the users cant get to the interent without the proxy setting on there pc's, All of them in the domain of the company. but some users use a proxy software and by pass the proxy server to open the non-authorized websites fromt he server.
I need to block them from my cisco router as my router is the end point of the company and I have my access lists there which allow users to go to the internet with or without proxy.
For example on the accesslist: I have 2 vlans, say vlan 1 connect on the internet directly wihtout using the proxy server, vlan 2 cant connect to the internet unless they have the proxy setting. but som users from vlan 2 use proxy softwares which on the report of microsoft says there is anonymus peopel opening this and this websites so they are using the bypassing proxy softwares but I need to block or deny it from my router for not getting outside the network without the proxy and not bypassing it.
