    Solved plex app vanished from firewall built-in app list

    Hello everyone, Who know I'm luckier here than posts in Synology Forum and Plex Reddit. I had a couple times in the last 2 years issues with an outside connection within plex as ilustrated below. I always could get rid of this kind of error by restarting DSM. This time it was diferent...

    Back up Firewall Rules?

    As far as I can tell, DSM provides no way to back up firewall rules. Configuration backup doesn't seem to do it, nor does Hyperbackup. Other than taking a screencap of my ruleset, and then retyping it all back in if I need to restore my system, does anyone know of a way to do this? Am I missing...

    Solved Block mac address within LAN for NAS

    DSM's firewall setting can block LAN IP address for access to NAS, but DHCP can always assign that PC a new IP, so ... could anyone tell me if possible or how to block a PC with its mac address ( this can be obtained from router interface) thanks!

    Info Port forwarding rules not have to generate firewall rules

    I just noticed the Setting button on the General tab of Network Center's Port Forwarding page. Throwing caution to the wind I clicked it and found three options. Two are for UPnP and I have UPnP disabled, but the third, when enabled, will auto-generate firewall rules for the port-forwarders...

    Firewall Rules: Allowed IPs and Threat Prevention?

    Quick question, but probably one that betrays how little I actually understand Threat Prevention at the moment. If I create a firewall rule that allows traffic from a range of IPs, will threat prevention just ignore those? I use a particular remote desktop streaming service that's generating a...

    Firewall Setup Question

    Hello, I have a question about my firewall setup. So far, I've not done anything specific to it. When the router was first plugged in, it asked me to set up a bunch of automatic rules, and I let it do that so I could get through the setup process. Presently, it looks like this: Some of this...

    Excellent Series of Synology NAS Tutorials-Mydoodads

    I bought my NAS a year ago and realise that, amongst other aspects, permissions, Photo Station and Moments had created a year-long confusion; well permissions had, partly because I did not start with groups as I had only one or two users. As far as Photo Station and Moments goes, after a short...

    Plex vs Firewall

    Something in my firewall settings blocks Plex from a direct connection. My settings are pretty basic.. 1. allow LAN IP range 2. allow VPN IP range 3. allow USA (all) and deny all else... When active I get no connection and when disabled I can directly connect. I'm stymied. Ideas? Thanks.

    What happens first: Firewall or Threat Prevention

    There's two approaches to applying access policies when there more than one engine: in parallel and in series. I'm forgetting which way it used to be on certain firewalls but it used to be important to know at which point onward routing, NAT, and firewall rules were applied and if any changes...

    Firewall rules for RT2600ac & DS1019+ & VPN

    I asked this over on reddit but didn't really get the info I needed, so hoping the experts at this new forum will be able to help :) I've recently setup a VPN on my RT2600ac router with SSL VPN and OpenVPN (not sure why I setup both, I guess I'm just playing around as I'm new to VPNs).
