Hi, > Trouble is, the IP addresses that access squid don't have host > names (ie. they don't exist) and they keep changing. Is there any way > to block access to this and is there a good FAQ, etc. there is a good FAQ at /usr/doc/squid/FAQ.html (belongs to web/squid). But you should not block these IPs, you should block all IPs and allow the IPs, which should have access. Bye Ralf
