I was able to download a port mapping utlility and ran a test. The router was able to pick this up in the UPnP section, thus i highly suspect my NAS is the culprit.   As i've been advised on how to manually enter port forwarding rules into the router (thanks), i'll close off the ticket and focus on the NAS and why it is behaving this way.   Many thanks for your support. ...

Hi, the UPnP list was populated until i reset the router.   I've managed to manually enter port forward rules on the router, this has been tested from within the NAS and also externally with ports visible.   I've also lodged a ticket with Synology to assess why this is occurring.   Are there any apps/services that i can run to simulate uPnP port forwarding rules to the router as i want to assess if th the router is misbehaving, and also how can i check the firmware version and access firmware updates, thanks. ...

Is there also a way to test if uPnP is wotking on the router ? It is enabled. Can i use another service to test it, and see the port mappings display on the router? Just want to isolate the problem, whether it's the router or the NAS.   Nothing has changed in terms of topology, etc. other than not being able to perform any port forwarding any more. ...

Please see my responses;   What model is your NAS? DS412+ On the Control Panel General screen, what is the Default Gateway setting? (Eg. LAN1 and IP address). 192.168.1.1 On the Network Interface screen, is that interface the only Connected interface? I have 2x interfaces, 192.168.1.100 and 192.168.1.101, with the default gateway on both being 192.168.1.1 And does the DHCP address match the default gateway address? Yes Does the NAS have a static local IP address (eg. 192.168.1.x)? I Am using static IP Addresses per the above. Does the NAS connect directly to Archer? Yes, dual ethernet ports, both connected to Archer. Are there any other devices connected to NAS or to Archer? No other physical devices, only wifi iPhones, iPads Check Log Center. Turn on all log settings for most details. See attached, this is all i get. ... View more
