23.1 Legacy Series / fq-codel problem forcing reboot

« on: July 13, 2023, 10:50:27 am »

Hi,

I'm experimenting with traffic shaping to get our bufferbloat under control. At the moment I'm just making small changes, retesting, noting the results and carrying on.

However, I've run into a problem with tuning fq-codel flows on my downstream pipe. It's currently set at 1024. I wanted to see what impact the values had through the whole range. If I set max value, opnsense reboots as soon as I hit apply and comes back with the gateway stuck offline. The only way to fix it is to restore a previous config and reboot again.

I've tried a number of values, down to 10000, it still causes the issue.

What's causing this and how do I get around it?

23.1 Legacy Series / How to diagnose brief losses of internet?

« on: June 19, 2023, 11:32:16 am »

I'd like to preface this by saying I've only just made my first OPNsense setup and that I don't know enough about the systems to know the optimal way to diagnose this issue.

I thought everything went ok, but I've noticed a complete loss of internet, twice, in the last few days. It only lasts 5 - 10 seconds. My ISP has been a little unreliable lately, so it could be them, but I'd like to make sure it's not something I've done.

I had a look through Log Files, but I'm not sure which area I'm supposed to be looking at and what category of log I should be filtering by. I'd be grateful if someone could point me in the right direction.

My setup is:

OPNsense 23.1.9
Optiplex 3020, 8GB RAM, i3-4130 (HT enabled) and a 120GB SSD.
HP NC365T (2 of the 4 ports used)
TP-Link TL-SG108PE
Unifi Flex Mini (connected to the TP-Link)

I have my ISP router in modem mode connected to one of the HP NC365T ports, set as WAN and the TP-Link switch on another of the ports, set as LAN.

I have C3 states disabled in bios and have enabled C2 states in tunables.

Many thanks.
