With netstat -a : I see the that squid handle correctly the client request
        WorldGate.eurofer.be:3128 pcGDL.eurofer.be:xxx ESTABLISHED
but squid does'nt return the page requested.
        gwWorld:32774 xx.xx.xx.xx:8080 SYN_SENT

the squid access.log file give the message :
        TCP_MISS/504 1026 GET http:.... - NONE/- -

The squid cache.log file content the message :
        TCP connection to proxy.skynet.be/8080 failed

If I remove this line :
 iptables -t nat -A PREROUTING -i eth0 -p tcp -dport http -j
REDIRECT --to-port 3128
all work
