I would like of a help of yours, in the following situations. I need redirect all request of port 80, to my proxy server with tproxy active, however it will not be gateway of my network. I am using Debian 5 Etch, kernel 2.6.19 in the two servers and iptables 1.3.7. However i did the following, i redirected of gateway to my proxy server using the command below; iptables -t tproxy -A PREROUTING -s 189.111.xxx.2 -p TCP --dport 80 -j TPROXY --on-ip 189.4xx.xxx.10 --on-port 3129 I got the error below in cache.log 2009/06/29 14:38:58| tproxy ip=189.111.xxx.2,0x2a07fbd,port=0 ERROR ASSIGN Then i did a DNAT rule, e.g below iptables -t nat -A PREROUTING -s 189.111.xxx.2 -p TCP --dport 80 -j DNAT --to-destination 189.4xx.xxx.10 and in proxy server the following command iptables -t tproxy -A PREROUTING -s 189.111.xxx.2 -p TCP --dport 80 -j TPROXY --on-port 3129 The request finised giving timeout. I would like know, if possible used tproxy in this situation. station <---------->gateway<---------->InterNet | redirected to proxy using iptables Proxy/Tproxy Regards
