22.1 Legacy Series / How to block access to OPNSense GUI

« on: July 06, 2022, 08:33:03 pm »

I have following Interfaces
Home (VLAN30) - 192.168.30.0/24
Surveillance (VLAN40) - 192.168.40.0/24

OPNSense IP are 192.168.30.1, 192.168.40.1, etc

I want to block Home network from accessing OPNSense GUI

I tried creating alias like this containing all OPNSense IP addresses



But this rule ended up blocking internet access altogether, what is the best way to block certain Interfaces from accessing OPNsense IP addresses without manually adding OPNsense address one by one for each interface?

1. Download the config.xml from your old machine (System > Configuration > Backups > Download Configuration)
2. Open the xml file
3. Replace anything that says "igb" with "igc"
4. Fresh install OPNSense in your new machine
5. Restore the modified config file into new machine (System > Configuration > Backups > Restore Configuration)

I always use this method without any issue, just remember to reinstall the plugin after restoring as you have to do it manually, after the plugin is reinstalled, all the previous configuration for each plugins will be restored.

Yep, that's it. I unticked the USB and it works now.

22.1 Legacy Series / [SOLVED] How to use LCDProc plugin?

« on: July 03, 2022, 08:44:38 am »

I have a box that runs OPNSense which has LCD with 4 buttons (up/down/enter/esc button) which is very common but how do I use the plugin? I've installed it but I can't find LCDd-sdeclcd.conf inside /usr/local/etc/. Do I have to create the file myself? I believe in pfSense, it has GUI under the Services menu.



UPDATE: For anyone who are interested. After installing the LCDProc plugin, I do have the LCDd-sdeclcd.conf inside /usr/local/etc/ (I was lazy and use the "find" command and I mistype the word, hence I can't find it), so you just need to modify the LCDd-sdeclcd.conf file, settings may vary based on your hardware, but for me the conf file content was

Code: [Select]

[server]

Restart the firewall and it works afterwards

Disable the "use USB" option. It dorsn't do what you probably think it does 

However, the cable that I used is USB to RJ45 Console Cable, which I assume is that I need to tick the "Use USB-based serial ports", so what's actually the option for? I will give it a try when I get home

22.1 Legacy Series / [SOLVED] No login prompt on console

« on: July 02, 2022, 07:51:58 pm »

I remember the first time I installed OPNSense, it's done via serial (with serial images). However after many updates, I no longer use the serial console port, but today I tried it but I can't seem to get the login prompt. It stopped after showing "SSH" text. 
 
 
 
I didn't get the "login:" menu. And my primary console is already set to serial. 
 
 
 
Any idea why?

Hardware and Performance / Certain port doesn't work on OPNSense even though it's detected (Imperva X1010)

« on: June 28, 2022, 12:22:14 pm »

I bought a 1u machine called Imperva Secure Sphere X1010, I never heard this vendor before so I opened the box and it's just a regular x86 with i3-2120, 8GB of DDR3, and 1TB WD Enterprise HDD. The thing has password which I don't know so I just went to BIOS and install OPNSense on it which is working fine except I can only use 2 out of 6 ports.

Here's the picture of the available ports


I can only use the em4 (MNG1) and em5 (MNG2). em0, em1, em2, and em3 are not working even though all of these ports are detected in OPNSense. When it's plugged, the light doesn't came up, it does on em4 and em5.

Here's the booting log from OPNSense (I replace the mac address with xx:xx...)

All ports detected in OPNSense (I replace the mac address with xx:xx...)

Valid interfaces are:

em2              xx:xx:xx:xx:xx:88

em4              xx:xx:xx:xx:xx:8a
em5              xx:xx:xx:xx:xx:8b

If you do not know the names of your interfaces, you may choose to use
auto-detection. In that case, disconnect all interfaces now before
hitting 'a' to initiate auto detection.
I checked the BIOS to see if there's any setting to enable them, but I can't seem to find anything


Anyone familiar with this kind of box can give me some insight on why the first 4 ports aren't working?

22.1 Legacy Series / Netflix on TV not working after using Unbound DNS Blocklist

« on: June 28, 2022, 05:58:15 am »

I recently enabled the Blocklist features under Services > Unbound DNS > Blocklist to block ads on network level and use all of the DNSBL list except the Blocklist.site.



After I enabled this feature, Netflix will give me tvq-pb-101 error code. I disabled it and it works fine again. How do I know which domain in the list is blocking Netflix?

21.7 Legacy Series / Not able to ping to another VLAN even though my firewall rules allow it

« on: January 09, 2022, 09:43:06 am »

192.168.20.21 is my CUPS print server 
192.168.0.7 is my printer 
 
I've created this rule 
 
https://i.imgur.com/blKecpq.png 
 
But I'm not able to connect to 192.168.0.7 from 192.168.20.21, if I remove the RFC1918, it works but I don't want subnet 192.168.20.x to be able to connect to other VLAN expect the one I specify. 
 
What am I missing in the firewall rule?

General Discussion / Casting (Youtube/Netflix/etc) not working on different VLAN

« on: January 02, 2022, 08:06:06 am »

I have VLAN for IoT. Chromecast and Google Home Speaker is one of them. I'm not able to cast audio/video to Chromecast/Google Home so I installed mDNS (os-mdns-repeater) plugin and turn it on for both IoT and my home network. 
 
The Google Home speaker works (I can now cast my audio from my phone/PC/etc), however I can't get Netflix/Youtube casting to work (it won't detect my Chromecast/TV with casting capabilities). 
 
Weird thing is I turn off mDNS and audio casting still works. 
 
Any idea why?

General Discussion / Question about the statement "don't use Native LAN (VLAN1)"

« on: December 31, 2021, 05:14:02 pm »

Hello, I'm not an expert.

But I kept hearing about the statement Native LAN (VLAN1) should not be used.

But I'm confused about the implementation. Assuming I have 2 ports in my firewall.

eth0: WAN
eth1: LAN - 192.168.1.x

Then I created 3 VLAN
vlan10: Management (eth1) - 192.168.10.x
vlan20: Home (eth1) - 192.168.20.x
vlan30: IoT (eth1) - 192.168.30.x

And I configure the firewall rules so that
1. vlan10 can access vlan20 and vlan30 but not the other way around.
2. vlan20 can access vlan30 but not the other way around.
3. vlan30 can't access other network.

And let's say I have 6 port switch.
sw0: uplink (connected to eth1)
sw1: vlan10
sw2: vlan20
sw3: vlan30
sw4: vlan10 for native, vlan20 and vlan30 tagged (connected to AP so it can broadcast SSIDs for vlan20 and vlan30)
sw5: untagged (this is where I configure everything)

Now that everything is done, what are we going to do with the sw5 or should I say the 192.168.1.x? By "don't use it", does that mean just leave it and make sure nothing is plugged/accessible by end user or do I have to disable it? Because if I disable it, I'm going to lose access to 192.168.1.x.

Can someone explain this concept to me.

Also, how do I get the switch to get 192.168.10.x IP address instead of 192.168.1.x without another port on the firewall? Or is it impossible?

21.7 Legacy Series / Re: Guest VLAN can't resolve DNS (I'm using Unbound for all my interfaces)

Hi

simply but a rule on top of the block rule to allow the traffic from the Guest net to the Guest address with port 53 (DNS) and IPv4 UDP or IPv4 TCP/UDP.

Thanks, works perfectly

21.7 Legacy Series / Guest VLAN can't resolve DNS (I'm using Unbound for all my interfaces)

« on: December 31, 2021, 11:13:14 am »

Hello friend, 
 
I'm using Unbound DNS for all interfaces in my network. 
 


 
I have a Guest network (VLAN100), I block this Guest network from accessing other network (RFC1918) in the Firewall rules. 
 

 
Unfortunately, that means the clients under Guest VLAN won't be able to resolve DNS. How do I block Guest VLAN from accessing private network (RF1918) but still allow the clients under Guest VLAN to resolve the DNS?
