Hi gang, I setup my firewall rules.
But now, DNS, Updates and ClamAV updates don't work anymore. Which rule am I missing?
I attached the firewall rules I have setup.
Thanks.

Hi gang, so nobody knows what the setting in the firewall for the DNS, Updates and ClamAV to work?
That window is hard to read. Run
iptables-save

Is this a public internet facing machine or is it on a home network behind a router?
Hi _DD_, it's behind a router but I will be turning on Plex to be able to be viewed by friends outside my network.

Hi subzero79, I will post the output tonight.
Thanks for your help.
Are you using public ip space in your home lan?
Since it sounds like you're behind a HOME router, your rules don't make a lot of sense with allowing that whole 256 IP public subnet. Your router is going to be doing all of the blocking from the outside world anyways.
By default everything is open in OMV firewall. So I would just delete all those rules in OMV and not worry about them. Let the router do all the blocking and just forward Plex ports to your internal address of the OMV machine. Unless you have a reason not to trust other users on your home network or if you have a very insecure home network to begin with.
Hi _DD_, even I give access to Plex directly to the internet, no one will be able to come through?
Are you using public ip space in your home lan?
HI subzero79, I don't have public IP. just the Plex service that points to my Plex server.
Then why that subnet 16.13.x.x?
Then why that subnet 16.13.x.x?
Hi Subzero, I always used that subnet, makes it different. No particular reason.
This is why I asked if it was behind a home router or was a public internet facing machine. If you have it directly accessible to the outside world then yes you need to setup your rules properly. But your rules don't make much sense even if it was facing the internet directly. So I would advise against doing that (i.e DMZ) and just forward the needed ports in your router. Much easier for you as far as work needed to do and the end result is a much safer machine.
Do us a favor though. Login to your OMV through an SSH session with putty and post a screen shot or the copy and paste the output of
Hi _DD_, so you recommend that I remove the rules since I'm behind my router and setup my router to port forward to the Plex server. That's safe enough?
I will post the results tonight for the ifconfig tonight.
But, just for my curiosity, what rule(s) would I have to put in so that DNS, updates and ClamAV updates would work or would you have an updated rules configuration then what tekkbebe posted a few years ago?
Thanks again for your help.
@mbourd25 that subnet is public address space. The whole 16.0.0.0/8 subnet belongs to Hewlett-Packard.
Private ip address space is defined here

Hi subzero79, that's my internal ips that I use in my home.
Also, I attached a screenshot of the results for ifconfig.
Thanks for your help.
There is a reason why private and public space exists. If you ever need to reach that public IP address you'll find trouble. Is unlikely, but that's the reason private space is reserved for nat networks.
I am still waiting for the firewall output in txt not an image.
Hi gang, I didn't know this would cause some problems since it was internal address.
But I will change all my internal IP addresses back to 192.168.0.0 tonight.
Thanks for showing this to me.
