You can have >a 'transparent proxy' which does not do 'transparent redirection'. You can do transparent redirection in -current . Take a look at the ipfw command 'fw', which lets you map a connection to another IP/port. its the same as the linux transparent redirection, which squid supports right. And yes, you can cache too with it. And yes, its a damn sight neater than using natd :) Just look at the squid FAQ on how to configure transparent redirection, there might even be a section in there for FreeBSD w/ ipfw 'fw' if memory serves right. -- Adrian Chadd <adrian@freebsd.org> To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
