Comments on: Adding One-to-One NAT on dd-wrt for a specific IP address to forward traffic like RDP http://www.omegaprojex.com/index.php/2009/03/27/adding-one-to-one-nat-on-dd-wrt-for-a-specific-ip-address-to-forward-traffic-like-rdp/ Just another blog from a computer nerd Tue, 23 Feb 2010 16:53:51 +0000 http://wordpress.org/?v=2.9.2 hourly 1 By: ElementZero http://www.omegaprojex.com/index.php/2009/03/27/adding-one-to-one-nat-on-dd-wrt-for-a-specific-ip-address-to-forward-traffic-like-rdp/comment-page-1/#comment-248 ElementZero Tue, 21 Jul 2009 15:01:01 +0000 http://www.omegaprojex.com/?p=588#comment-248 I believe what you want is <code> iptables -I INPUT -p tcp -d $(nvram get wan_ipaddr) --dport 80 -j ACCEPT </code> Which will open up port 80 on the router itself to on the WAN IP (just change the port to whatever you need). Optionally you could do this as well <code> iptables -I INPUT -p tcp -d $(nvram get wan_ipaddr) --dport 80 --source WAN_IP -j ACCEPT </code> where WAN_IP is a public addess you would like to allow. This will limit the open access to only specific IP's if desired. Let me know if this doesn't meet your needs and I can get you the right script. I believe what you want is


iptables -I INPUT -p tcp -d $(nvram get wan_ipaddr) --dport 80 -j ACCEPT

Which will open up port 80 on the router itself to on the WAN IP (just change the port to whatever you need). Optionally you could do this as well


iptables -I INPUT -p tcp -d $(nvram get wan_ipaddr) --dport 80 --source WAN_IP -j ACCEPT

where WAN_IP is a public addess you would like to allow. This will limit the open access to only specific IP’s if desired.

Let me know if this doesn’t meet your needs and I can get you the right script.

Port forwarding is not working in this case due to the fact the port that has to be opened is in the router itself and port forwarding only works for all other devices other than the router in the network. To put it short how do I access a specific port in my DD-WRT router, I only know how to access ports for other devices in my network.
