Hi,


I'm trying to open the web interface of the archer C9 in my router. I configure the nat in the same way i have configured sucessfully other devices in my company router, but it doesnt work. I have natted (i'm not sure if the expressión natted is right, sorry but i'm spanish) the port 80 of my c9 router to 9080 in my dsl company router and i have configured the remote management ip to the one I'm using to connect through internet. For example, the same configuration to open ssh port of one computer in my lan to 2222 in my dsl company router and I can connect sucessfully. With ftp port i have the same problem (20-21 ports to 9020-9021 ports)
Is there any kind of restriction to access to this ports when the router is not connected directly to internet?


Thanks and regards.
