Hi, after reading manuals an two days searching in the internet for a solution I try this way: The following I want to reach: In my clients (Firefox and filezille) I configure the acces via proxy GateKeeperOut port 3128. Each access should be authenticated against my W2K server. Each access should be watched by squidGuard. HTTP access should then be forwarded to the transparent http proxy GateKeeperOutHTTP port 9080. FTP access should then be forwarded to the transparent ftp proxy GateKeeperOutFTP port 9021. The http access alone works fine from browser over squid and squidGuard to the transparent proxy and out. ftp I getn't work. Any ideas?
