Nightmare with virtual server

[Khurram]

Thanks for your reply. So I do not need any FORWARD or INPUT chain rules? I will try it out on the router.

What if I want to forward a port to another port on the router itself. For example, forward port 33425 to port 22 on the router itself (I do not want to open port 22 itself to the outside). Will I need some other rules in this case?

It should work like this, other chains already have been made

iptables -L

you could use the same command, just use the LAN ip of the router as endpoint

if you want to open a port in a regular way just use:

iptables -A INPUT -p tcp --dport 80 -j ACCEPT

or something like that
