Hi, just another question. Let my router be 192.168.7.33 with interfaces eth0 and ppp0; then this works perfectly here: # iptables -t nat -A PREROUTING -i ppp+ -p tcp --dport 80 \ -j DNAT --to 192.168.7.49:80 However, I want to request from inside my local domain the same way. This seems to end in a drop or an infinite loop: # iptables -t nat -A PREROUTING -d 192.168.7.33 -p tcp --dport 80 \ -j DNAT --to 192.168.7.49:80 Besides that I want to know what is going wrong here, I further would like to ask how I could debug this. Thanks in advance. Bertram -- Bertram Scharpf Stuttgart, Deutschland/Germany http://www.bertram-scharpf.de
