Hi List I have FC6, FC5, CentOS and Mepis boxes in my network. I have a proxy which filters web access. I want to be able to force the entire network to use the proxy. Currently I've simply gone to firefox and added the proxy to the connection settings - however any user could change this back to direct connection if they wanted to... How can I force the network for each box to use the proxy and basically not work at all if the user tries to use a direct connection to the internet? Thanks in advance
