22.7 Legacy Series / Throughput with IDS/IPS Enabled

« on: November 11, 2022, 11:39:05 pm »

Good Day Everyone,

I have been trying to wrap my head around the Intrusion Detection system. I have attached screenshots of the configuration that I have instead of trying to explain it all. The long and the short of it is that when I have Intrusion Detection/Intrusion Prevention enabled I see the throughput of my WAN drop from 550ish to 480 or so.

I have attached screenshots of everything I can think of. Is the IDS system just that much of a power hog? If so perhaps the system requirements page needs an update to reflect this because from my understanding I should be running a lot better than I am. I do know I'm a little light on RAM that is being addressed tomorrow when my order shows up (I hope). For the observant among you this is a virtualized install with a passed through Intel dual gigabit nic.

Thanks in advance,

22.7 Legacy Series / Proxmox Internal Error after upgrade from 22.7.6

« on: October 16, 2022, 04:02:08 am »

Good Evening Everyone,

I am running Opnsense inside a Proxmox VM with a dual port Intel NIC passed through to the VM. I tried to install the update from 22.7.4 to 22.7.6 several times now and each time I do the update appears to complete and in the course of rebooting the whole thing stops responding and I see a yellow triangle next to the VM name which when I hover over it gives me a little textbox that says "Internal Error". I cannot boot the VM without restoring a backup I took prior to the upgrade which effectively rolls me back to 22.7.4

I'm having another issue involving IDS but I'll save that for another thread once I get this upgrade working. I would prefer not to build a new VM and install a fresh copy of Opnsense. I could if I have to but I'm hoping I don't.

Anyway thank you for your thoughts!

19.1 Legacy Series / Insight problems

« on: April 17, 2019, 03:20:58 pm »

Good Morning Everyone,

I am a recent convert from that other "sense" firewall to OpnSense. Loving OpnSense so far!

I am having one problem that is not making sense to me. Specifically with Insight. Earlier in the day yesterday Insight was reading all my traffic, making fantastic graphs that I found very "insight"-ful (see what I did there?) with regards to how traffic was moving from the web through my network (Multiple VLANS, etc). All was good in the land. However about 6:40 or so last night that all stopped working. I had been adding rules to my firewall about that time to allow access to various servers in the network at the time it stopped working fo I'm wondering if I messed something up there.

Steps I have taken to remedy the issue:

• Remove Firewall rules
• Reset Router configuration to prior know working configurations

[ii]Reset data, repaired database, etc. (All of these steps has "Minimal success" in that I am now able to get "a little traffic" to show up on the graphs but only for one VLAN and graph's are not accurate.[/ii]
[/list]

I am sure there are other steps that I took as well but they all revolved around trying to figure out what I broke and undo it so it involved adding and removing firewall rules, NAT rules, etc.

I am sure you'll need to see logs and I will provide them once I know what logs you need and how to access them as I am still learning this product.

Thanks in advance.
