Hello! Running fetchmail from the mailserver behind the firewall I have the problem to go to the WAN. It works as long as I stay within the LAN. iptables -t nat -A PREROUTING -p TCP --dport 110 -m state --state NEW,ESTABLISHED,RELATED -j DNAT --to 192.168.1.75:110 But writing iptables -t nat -A PREROUTING -p TCP --dport 110 -m state --state NEW,ESTABLISHED,RELATED -j DNAT --to 0.0.0.0:110 I get a kernel: martian destination 0.0.0.0 from 192.168.1.3, dev eth0 Must I install fetchmail on the firewall? Is this the only way to go? -- Andreas Meyer Object Class Common Name userPassword posixAccount andreas {SSHA}hpyqObx1/BXbKFgXoqCayoGsvIgPYiVc
