Subject: Forwarding problem, :( port redirection!
Date: Mon, 24 Feb 2003 16:12:51 +0800 [thread overview]
Message-ID: <045a01c2dbdc$8964ae00$0b00000a@nocpc3> (raw)
Im trying just to forward simple ftp, 21 request into my internal machine.
Im typing this but it does not work..
any ideas?
iptables -t nat -A PREROUTING -i eth0 -p tcp -d 10.0.0.11 --dport 21 -j
DNAT --to 203.190.72.108:21
iptables -A FORWARD -i eth0 -o eth1 -p tcp -d 203.190.72.108 --dport 21 -j
ACCEPT
eth0: Internet
eth1: LAN
Doc: http://www.knowplace.org/netfilter/syntax.html#conf6
================================
Destination NAT the packets (changes the destination IP address in the IP
header and port number in the TCP/UDP header)
iptables -t nat -A PREROUTING -i eth0 -p protocol -d
ip_address_of_eth0 --dport original_port_number -j DNAT --to
destination_ip_address:destination_port_number
Forward the natted packets (allow the natted packet to be forwarded)
iptables -A FORWARD -i eth0 -o eth1 -p protocol -d
destination_ip_address --dport destination_port_number -j ACCEPT
================================

thanks,
