19.1 Legacy Series / Re: Create report from LOG

« on: February 15, 2019, 12:41:04 am »

Thank you Franco, Splunk is powerful but it isn't what I'm lookin for.
I'm searching for something simple like LogMX.
1. I export LOG from the last 30 days in CSV format from Reporting - Insight - Export - FlowSourceAddrDetails
2. I import them in a simple software
3. the software resolve the hostname of the public IP

Any other idea?

Development and Code Review / Re: Sensei on OPNsense - Application based filtering

« on: November 23, 2018, 11:57:10 am »

Good morning, will Sensei one day consume less resources in terms of RAM and CPU?
For example an Atom CPU or a Celeron with 4GB or 8GB of ram?

18.7 Legacy Series / Outbound NAT rules not instantly applied

« on: November 22, 2018, 12:04:05 pm »

Hello, I've found on different OPNsense firmware version that NAT rules are not applied until I reboot OPNsense.
Outbound NAT is in Manual outbound NAT rule generation (no automatic rules are being generated).
It's there a way to reload Outbound NAT without reboot?

18.7 Legacy Series / Help creating weekly report

« on: November 21, 2018, 11:29:10 pm »

Hello, I need help or suggestion with creation of OPNsense report.
The first report that I need is weekly report of Social Network usage:
- global;
- per source MAC address or source IP;
- can I specify what Social Network? For example Facebook?

The second report is daily with bandwith usage:
- global;
- per source MAC address or source IP;

In both report can I resolve destination IP to display the FQDN of destination?
Thank you

18.7 Legacy Series / IDS IPS with Suricata and OPNsense in Transparent Mode

« on: August 22, 2018, 05:30:00 pm »

Hello, I'm trying to make working Suricata with OPNsense in Transparent Bridged mode.
According to this page:
https://docs.opnsense.org/manual/how-tos/transparent_bridge.html
I must setup (Suricata) Interface on WAN or BRIDGE or LAN?
What about (Suricata) Home Networks: blank (any) or the broadcast address of the transparent network?

I need to know how it's configured to work, for example: if I set only WAN as interfaces
A packet arrives from WAN, pass through Suricata and then it goes to BRIDGE?
PACKET --> WAN --> SURICATA --> BRIDGE --> LAN
or
PACKET --> SURICATA --> WAN --> BRIDGE --> LAN

Can I suggest to insert this settings of Suricata on OPNsense Web Configuration Page?
https://github.com/StamusNetworks/SELKS/wiki/Initial-Setup---Suricata-IPS
interface: WAN
threads: 4 # or a number that is below half the number of cores available
defrag: yes
cluster-type: cluster_flow
cluster-id: 98
copy-mode: ips
copy-iface: LAN
tpacket-v3: no
ring-size: 2048
use-mmap: yes

interface: LAN
threads: 4 # or a number that is below half the number of cores available
defrag: yes
cluster-type: cluster_flow
cluster-id: 98
copy-mode: ips
copy-iface: WAN
tpacket-v3: no
ring-size: 2048
use-mmap: yes

With the availability of this settings, I can make a transparent firewall with 3 interfaces:
em0 Management of OPNsense with IP
em1 WAN without IP
em2 LAN without IP
in this mode I don't need to create a bridge and all traffic is copied from "copy-iface:" option in Suricata (transparent).
The rule can be written on WAN or LAN indifferently.

Thank you for any precious help

18.1 Legacy Series / [SOLVED] Re: Problem with VIP CARP MASTER redundancy

« on: April 27, 2018, 04:10:38 pm »

The problem was the switch installed on WAN
Extreme Network X430
https://www.extremenetworks.com/product/x430-series/

Changed with another and the problem was gone, I think is IGMP Snooping problem like this post

The other problem is that the connection speed slow down because both want to be the master.
Problem with OpenVPN, both reply on WAN.
If you shutdown, for example, the backup firewall, the connection speed drastically increase.

18.1 Legacy Series / Re: DNS problem between Viscosity on OSX and OpenVPN on OPNsense

« on: February 12, 2018, 03:57:18 pm »

Make sure Unbound has your VPN Subnet in there. By default, it only does the /32 and won't work.

I have a separate entry there for my VPN Network.

Thank you.
You are right, there is no VPN Subnet in Unbound Access List
