Hi, I want to redirect local http traffic to a transparent squid porxy running on the NAT box itself. I've used : # iptables -t nat -A OUTPUT -p tcp -m owner --uid-owner squid -j ACCEPT # iptables -t nat -A OUTPUT -p tcp --dport 80 -j REDIRECT --to-ports 3128 But this works no more with kernel 2.6.11 & later. # iptables -t nat -L -v gives this --------------------------------------------------------------------------------------------------- Chain PREROUTING (policy ACCEPT 2281 packets, 906K bytes) pkts bytes target prot opt in out source destination Chain POSTROUTING (policy ACCEPT 97012 packets, 5712K bytes) pkts bytes target prot opt in out source destination Chain OUTPUT (policy ACCEPT 97005 packets, 5712K bytes) pkts bytes target prot opt in out source destination 0 0 ACCEPT tcp -- any any anywhere anywhere OWNER UID match squid 0 0 REDIRECT tcp -- any any anywhere anywhere tcp dpt:http redir ports 3128 Chain loc_dnat (0 references) pkts bytes target prot opt in out source destination Chain wlan0_masq (0 references) pkts bytes target prot opt in out source destination --------------------------------------------------------------------------------------------------- TIA, Djalel
