Port forwarding on R7000 not working (fiber & VLAN)
Hi all, Last weeks I have been puzzling with port forwarding on a R7000. I hope someone can help me out here. Setup: Fiber (1 Gbit) connected to Optical Network Terminal (ONT) little white...
Hi all,
Thanks for helping out. I found the solution. The problem was on my NAS (the DNS server on BOND 1 was false). After giving the NAS a static DHCP and on the NAS set this on ' automatic' the connection was resolved.
After all it was a rookie mistake. However, the learning is that if your port scan gives a state FILTERED or STEALTH, the port is actually open, but the application on the internal LAN is not correctly configured.
Cheers
Be sure your disabling uPnP if your setting up any PF rules.
Might be something to check with the NAS Mfr for help and support regarding there product.
Hi FURRYe38 ,
Thanks, I disabled the UPnP function, but that did not have the desired effect. Whu do you think the problem could be with the Synology NAS? The router setup on synology cannot be completed, because the ports cannot be opened.
Are you trying to access the NAS from outside the LAN? Really is not recommended to put NAS accessible from the WAN side for security reasons.
I'd review some info here and see if it helps:

Possible that your ISP VLAN maybe a factor as well.
Port forwarding is a security risk indeed, but the port forwards the route to the IP address on the LAN network. And there a synology NAS with a fine firewall has its own security on the ports used by the NAS. So there is no specific additional risk (assuming the security of Synology is of the same quality than the Netgear security)
I agree it could be the VLAN, but how?
