problems to redirect a port

Hello I have a router and a firewall

This is the environment. I need to connect to computer with remote admin in 65531 port.
 
In the zyxel router I have enabled the nat

Port forwarding all the ports to the netgenie firewall.

When I try to connect to the remote admin computer, in the zyxel router I see in the log that the tcp connection has been reset three times.


In the netgenie I have set another port redirection to the computer IP …
 

And I open the firewall for these ports.
 
But In the firewall log only see the connection tries to the port 8000 not for the 65531 remote admin port.



So I think the zyxel router are droping the connection.

I have taken some screenshot to make It look easier.

thanks

OK - Turn of NAT on the ZyZel M8 Like this

ZyXEL - Router Setup (Public IP Range)

Then you only have to port forward on your firewall.

well it's an option, but I prefer not to do it because It's a business router and I don't want to stop it.

It's possible look for another solution?

thanks
