confirm 587515 I would like make a transparent proxy, transparent for both the client and the server. But my problem is that the transparency works for the client but not for the server. Could you please help me ? My configuration : client ------------- tproxy+zorp2.0 (debian woody) ----------------- server 192.168.100.199 192.168.100.135 192.168.0.134 192.168.0.251 My policy.pl : from Zorp.Core import * from Zorp.Plug import * from Zorp.Http import * Zorp.firewall_name = 'zorp@site' InetZone("site-net", "192.168.100.0/24", outbound_services=["intra_http"], inbound_services=[]) InetZone("local", "127.0.0.1/8", inbound_services=["*"], outbound_services=[]) InetZone("internet", "0.0.0.0/0", inbound_services=["*"], outbound_services=[]) class IntraHttp(HttpProxy): def config(self): HttpProxy.config(self) self.transparent_mode = TRUE def zorp_http(): Service("intra_http", IntraHttp,router=TransparentRouter(forge_addr=TRUE)) Listener(SockAddrInet("192.168.100.135", 50080), "intra_http") My iptables.conf : *filter -P FORWARD ACCEPT -A INPUT -m tproxy -j ACCEPT COMMIT *tproxy :PREROUTING ACCEPT :OUTPUT ACCEPT :PRintra - -A PREROUTING -i eth0 -d ! 192.168.100.135 -j PRintra -A PRintra -p tcp --dport 80 -j TPROXY --on-port 50080 COMMIT Philippe LUCAS
