AC-68 and Synology NAS uPnP issues

[scyto]

Hi, I am having issued with Synology DS1815+

The unit supposedly supports AC68 etc, but with both stock and merlin firmware all uPnP outbound portmappings are lost after a few days and never re-established.

The DS1815+ has a strange 'router configuration' system which sometimes finds the router and sometimes doesn't. Once it finds the router it establishes whatever outbound upnp ports I want. However after a few days / a week those port mapping are lost and never re-established. I have logged a ticket with Synology. I also just decided to static map by synology (instead of upnp to see if that helps - but it has never drifted IP add).

Has anyone seen this? Has anyone here got a DS1815+ or similar that works flawlessly?

Alex
PS I don't want to turn off uPnP so please don't suggest that (and no it is not a security risk)

forward port 80 to your nas on the router.

forward port 80 to your nas on the router.

Thanks, but not the answer I am looking for. I will NEVER forward port 80 - only 443 secured with a HTTPS certificate. The point is I do not want manual port forwarding, I want to use the uPnP engine of the Synology to open these and many other port for many other services, I don't want to maintain manual port mappings.

Ha < i see. cant help you there im afraid, personally i have ports forwarded manually, but you right synology nas (dsm 5.2) occasionally wipes all my ports forwarding rules in the router, really annoying.

Another thing the synology nas Upnp engine can only foward 32 ports on asus routers and when it tries and fails it wipes all previous rules on the router.

The miniupnpd daemon by default automatically cleans rules that it thinks are stale. You might try disabling this feature by

nvram set upnp_clean=0
nvram commit

and reboot

Thanks, I will try, I assume I have to SSH into the router to do this?

Also I think it will turn out to be bug in the synology, I changes the dynamic IP (192.168.1.123) to manual (192.168.1.4) and while the plex server running on it correctly updated the port. the synology mapping app didn't - you can see the ports here in the asus, where they 123 addresses never got changed to 4 addresses by the upnp app in the synology.

Yes, sorry.....enter the commands via telnet or ssh to the router.

Have you updated to the latest DSM?

 

[scyto]

Have you updated to the latest DSM?

Absolutely:


DS1815+
DSM 5.2-5592 Update 2
Uptime: 7 day(s) 22 hour(s) 39 minute(s) 40 second(s)

(the upnp issue started maybe about 5 days ago, so I guess the issue can repro in less than a few days)
