Why do you believe it's a loop? Please show tcpdumps. Loop will be visible on loopback (tcpdump -nlilo). > How can i change this???

However I doubt it's a loop, I think REDIRECT never apply to locally generated packets. I keep this comment on top of my firewalling scripts: ### filter This is the default table (if no -t option is passed). It contains ### the built-in chains INPUT (for packets coming into the box itself), ### FORWARD (for packets being routed through the box), and OUTPUT (for ### locally-generated packets). ### ### nat This table is consulted when a packet that creates a new connection ### is encountered. It consists of three built-ins: PREROUTING (for ### altering packets as soon as they come in), OUTPUT (for altering ### locally-generated packets before routing), and POSTROUTING (for ### altering packets as they are about to go out). ### ### mangle It had two built-in chains: PREROUTING (for altering incoming ### packets before routing) and OUTPUT (for altering locally-generated ### packets before routing). Recently three other built-in ### chains are added: INPUT (for packets coming into the box ### itself), FORWARD (for altering packets being routed through the ### box), and POSTROUTING (for altering packets as they are about to go ### out). ### ### ...iface... ...iface... ### | ^ ### v | ### -mangle,NAT- -mangle,filter- -mangle,NAT-- ### |PREROUTING|-->[Routing]-->|FORWARD |-->|POSTROUTING| ### ------------ | ^ --------------- ------------- ### | | ^ ### | +--if NATed------------+ | ### v | | ### -mangle,filter- -mangle,NAT,filter- ### |INPUT | +->[Routing]->|OUTPUT | ### --------------- | ------------------- ### | | ### v | ### ...
