Do the hosts in your LAN have a default gateway, i.e. does your DHCP server pass out a router option with the leases? Check with "ipconfig" on Windows or "route" on Linux hosts. > cat /proc/sys/net/ipv4/ip_forward is 1 > > What are routes I have to create with route command ? Normally you shouldn't have to create any for that kind of setup. Please post the output of "iptables -nL" and "iptables -t nat -nL". > How can I routed 80 port to 10.20.30.1 with iptables ? That is called port-forwarding, not routing. It's done via DNAT. See [1] for instance.
