We are a medium ISP with several wireless clients and recently we upgraded from Freebsd 4.8+Squid 2.5 Stable4 to Freebsd 6.0+Stable12 compiled with the following options: Squid Cache: Version 2.5.STABLE12 configure options: --prefix=/usr/local/squid --enable-snmp --enable-storeio=diskd,ufs --enable-ipf-transparent --enable-err-language=Portuguese --enable-default-err-language=Portuguese --enable-delay-pools --enable-underscores --enable-removal-policies=lru,heap --with-pthreads --with-dl --with-aio After this upgrade we are having the following problem with Squid+transparent proxy: *ONLY* clients that have some kind of router like Dlink DI-604 or Linksys (etc) can't surf the web after +- 30/40 minutes squid was started. All others things like email (pop3/smtp), icmp, ftp, etc, etc works great. The user simply can't use your browser. If the same user put your connection direcly in a machine (bypassing the router), surf in the web is OK. Any idea?
