hi all, I m having a problem with squid 2.5 stable1. Often it gives an error '(113) no route to host' but if I restart squid it works fine for about 15 to 30 mins. squid is accepting connection on port 3128. I have also few iptables to accept connection from the internet and nat to another server (on the internal network). The ports I am accepting from the internet are 80, 8000, 25 and 110. does any one have an idea of what is the problem. if any one needs more info please tell me..... below is a piece from the cache log while trying to access hotmail and the error occurs.
