Hi !!! I installed squid 3 stable on a Debian box, with 1Gb of RAM, 160 Gb of disk and AMD Optreon Dual Core, in transparent mode. The squid box have only one nework card and public IP. I have a Mikrotik router-box, and in this machine I have configured to send al http request (port 80) to port 3128 of my squid box. Everything seams work find, but sometimes I have very low performance in tranfers duration. I note in the cache.log that I have a lot of warnings messages with "forwarding loops detected", is the only error or warning I found. I don't put any routing rules in my squid box. It's ok? May be I have a configuration problem. Any Help? Thanks a lot !!! Ramiro
