firewall

Hello, My question revolves around the Synology Firewall and IPSET integration. Setup is a DS918+ for a small company (5 office workers). They have a subdomain and have to share links with the outside world/file upload requests. They have both internal and remote users. We have forwarded...

Hi everyone, this is my first post on the forum although I've been passive reader for a while now. I posted a doubt yesterday on the synology subreddit but it doesn't seem to have attracted much feedback, so I though maybe you people would have some insight. I'm copying below what I wrote...

Recently I've lost the ability to reach my NAS file when my phone is connected by VPN Server. I've discovered that dropping the firewall allows me to see the NAS files. I'm puzzled by what firewall rule I need to add to obtain SMB file access. I've allowed the VPN IP range...

Hello, I am trying to utilize the firewall on my ds918+ to limit access to ports on my synology to static ranges within 192.168 and have run into an issue were in order to get my docker containers to play nice with each other I have had to unblock their subnets completely (IP 172.17 and...

I'm a newbie to all this and have started setting up my DS920+ which is really only going to be used as a SMB share for a small business and was wanting to setup some firewall rules to only allow specific internal local IP address through and block all others. How do i do this and i assume i...

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...

My current setup: I have a SRM2600ac router and a couple of Netgear switches, one is a PoE switch for external PoE cameras. Those cameras record to a NVR (BlueIris) internally, those cameras and the NVR don't have a gateway address and they are also are set up in the firewall to be denied access...

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...

Hi! First time poster here. Bit of background before my question: I've got a 213j in my flat and a 115j at my parents house, they are both used to store backups of local PC's. I've recently started looking into how I can make better use of both NAS's and wanted to use each NAS as an off-site...

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...

I have my DS718+ running a vpn server with openvpn protocol. LE certificate is valid. I can connect and view my cameras through Blue Iris ios app (BI is hosted on a local computer). However, when I connect my laptop to the vpn when travelling, I can't access my drives on the DS. Is one of...

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...

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...

Does the synology firewall handle IPv6 now? They says on the following page that it isn't but maybe things changed since: 10 méthodes pour sécuriser l'accès de votre NAS Synology

I've enabled the NTP service on the router so that certain devices can use it. Is this rule needed and is it allowing outside sources into the network?

I'm trying to block a device from accessing the internet as well as the internet accessing it. This is more of a precautionary step. Please see attachment, do I have the settings correct?

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.

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...

I'm running a vpn server on my DS (openvpn) and port forwarded from my router to the DS. It has been working fine but I wanted to check if others agreed with my settings. I tried to follow what babylonia posted here. 1 - Allow/Deny rules at the bottom of the image - just noticed that my WAN...

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). I want...
