Is this possible with Iptables

[adams]

I am running custom frimware (kfurge). can somebody tell me if the following setup is possible using Iptables?

I want the router to take incoming requests on wan from all ipaddresses on the internet and route them to a particular LAN ipaddress on different port.

Heres an eg to better illustrate what i want.

A request for eg on port 80 from the internet should be intercepted by IPTables and routed to my internal webserver running on port 8081 on IP address 192.168.1.5 ...(router IP address is 192.168.1.1)


thanks

i think you could use the virtual server in the webui... that should do the job.

try
iptables -A FORWARD -p tcp --sport http -d 192.168.1.5 --dport tproxy -j ACCEPT

If it doesen't work with -A try with -I but that wont be a problem
