My merchine eth0 is 192.168.8.50 modprobe iptable_nat echo "1">/proc/sys/net/ipv4/ip_forward iptables -t nat -A PREROUTING -i eth0 -p tcp --dport 80 -j DNAT --to 192.168.8.55:80 I enter "iptables -L" and it shows all default policy are accept. apple:/# iptables -L -n -t nat Chain PREROUTING (policy ACCEPT) target���� prot opt source�������������� destination DNAT������ tcp� --� 0.0.0.0/0����������� 0.0.0.0/0���������� tcp dpt:80 to:192.168.5.55:80 Chain POSTROUTING (policy ACCEPT) target���� prot opt source�������������� destination Chain OUTPUT (policy ACCEPT) target���� prot opt source�������������� destination However, I use linx to http://192.168.5.50, I got "lynx: Can't access startfile http://192.168.5.50/" I can browser 192.168.5.55 directly using lynx.
