Tutorials and FAQs / Uploading Custom Suricata Rules with the GUI?

« on: November 18, 2024, 10:43:01 am »

Is there a way to upload custom Suricata rulesets using the GUI? At one point we use to be able to do this but it doesn't look like its availaible any longer. Here was an old way:

Step 1: Navigate to the Suricata Settings

    - In the OPNsense dashboard, go to Services > Intrusion Detection.
    - Click on the "Signatures" tab.

Step 2: Add Custom Suricata Rules

    - Scroll down to the "Local Rules" section.

 Here, you can add custom rules directly into the Suricata rule configuration:
 You can paste the contents of your custom rules into the box.
 Alternatively, you can specify a custom rule file location (more advanced).

General Discussion / Cannot Brridge LAN & Wifi

« on: October 11, 2018, 08:12:30 pm »

Every time I follow these instructions to bridge my LAN & WIFI card I get this error:

Bridging a wireless interface is only possible in hostap mode.

How do I bridge Lan & Wifi?

Trying this: https://forum.opnsense.org/index.php?topic=5066.0
and this: https://www.cyberciti.biz/faq/howto-configure-wireless-bridge-access-point-in-pfsense/

Wifi card is a Dell DP/N: 0MX846.

Also tried a Realtek RTL81878 MOW 11b/g and got the same error.

Intrusion Detection and Prevention / Whitelist IP address Blocked By Suricata

« on: August 24, 2018, 07:39:00 am »

I'm using Suricata IPS. It keeps blocking a single specific IP address with a rule. I would like to keep the rule in place just not block the single IP. What is the correct way to whitelist the IP address so it is not blocked with the Suricata IPS rule?

18.1 Legacy Series / Intrusion Detection - Rules Selection Bug/Annoyance

« on: February 22, 2018, 01:39:58 am »

Go to:  Services>Intrusion Detection>Administration>Rules

Browse past page 6 of rules, for the example.
Then click a box to enable any rule (furthest box on the right of rule).
This bring you back to page 1 automatically.

This is very annoying while browsing each page and trying to enable individual rules. You have to remember which page you are on to go back and continue where you left off. Enabling a rule should keep you on the same page you enabled the rule from.

General Discussion / Transparent Filtering Bridge problem

« on: September 20, 2017, 07:23:57 pm »

I am trying to create a transparent filtering bridge.
My setup is: Internet-->Opnsense Filtering Bridge-->Router-->Lan
I followed these instructions: https://docs.opnsense.org/manual/how-tos/transparent_bridge.html?

Step 4. "Now Add an IP address to the interface that you would like to use to manage the bridge. Go to Interfaces -> OPT1 enable the interface and fill-in the ip/netmask." I think these instructions are outdated here. There is nowhere to enter the IP. I assume I can do this by going to Interfaces -> LAN & Interfaces -> OPT1, change the IPV4 configuration type to static and then set the IP address which I did to 192.168.1.3.

My Bridge OPT1 is 192.168.1.3
My Router is 192.168.1.1

I cannot access the Opnsense firewall any longer, but the bridge works.
Any ideas?

General Discussion / Cron GUI Bug

« on: August 29, 2017, 02:49:07 pm »

If you go to:
Services--> Intrusion Detection--> Schedule

It immediately defaults to a Edit Job option. I am unable to view the rest of the crons
or go to another cron to edit. The only way to edit or create another one would be to quickly
click on the edit icon or the + icon to add another cron before the screen goes back to the
Intrusion Detection settings page.

I know there are instructions on how to do this on PFsense:
https://doc.pfsense.org/index.php/Redirecting_all_DNS_Requests_to_pfSense

But if someone has already done this on their Opnsense box, please post a screen capture of it or the exact configuration of yours as it is laid out in Opnsense.

General Discussion / Setting up a Bridge - Multiple NICs to act like a switch, like a SOHO router

« on: May 04, 2016, 04:38:36 am »

I have been looking for some good instructions on how to set up a bridge to have multiple NICs to act like a router (Bridge the interfaces to act like a switch, like on a SOHO router). The OPNsense guide doesn't really have much on setting one up, only a transparent filtering bridge.

I tried using these instructions for creating a bridge which is for PFSense. The process is nearly identical if not the same as OPNsense on how to Bridge Multiple Lan ports/NICs to act like a router.

My setup looks like this:
0 WAN, 1 LAN, 2 NIC, 3 NIC - I want to get NICs 2 & 3 on the same network as the LAN and lease out IPs on the same network: 192.168.1.2-192.168.1.255.

It seems I cannot get the bridge/NICs to function properly. I can get DHCP to work where other PCs are issued IP addresses but no WAN.

Are there any instructions for this specifically for OPNsense?
