Synology nas and upnp

Hi
I install openwrt on dsm with vmm
I got a problem when I try to add the bot from synology Nas to openwrt through the upnp program, the synology Nas device recognizes openwrt
Then I get a message that says

Failed to save all port forwarding rules. Please make sure the following
requirements are met:

  1. UPnP/NatPmP protocol is enabled.
  2. Number of port forwarding rules does not exceed the maximum number allowed on the router.

Not sure that understood you, but probably you need to install miniupnpd and luci-app-upnp and enable it.

Go to Luci / Services / UPnP
http://192.168.1.1/cgi-bin/luci/admin/services/upnp and check all these:

  • Start UPnP and NAT-PMP service
  • Enable UPnP functionality
  • Enable NAT-PMP functionality

On the same UPnP page in the "Active UPnP Redirects" you'll see a list of forwarded ports

Thanks for answering the questions
I have already downloaded the two files and they are activated
