General Discussion / High latency pinging the Opnsense LAN interface

« on: November 08, 2023, 09:52:10 pm »

Still observing random high latency pinging the Opnsense LAN interface 192.168.1.1 From the same PC I am pinging two other internal IP's 192.168.1.2 and 192.168.1.192 with no latency issues.
This is really annoying because my latency-sensitive voice applications (internet-based) don't like it.

General Discussion / High Latency - every 8 hours

« on: November 07, 2023, 03:01:07 pm »

I am observing high-latency pings to the local wired Interface of the Opnsense firewall from the LAN. Starting at 4 am (CET) latency climbs to 2500 for about 2-3 minutes, repeating every 8 hours.

I can replicate the issue on every interface. For troubleshooting purposes, I have configured a new interface put a Windows machine in the newly configured Network, and connected it with an ethernet cable directly to the Opnsense firewall, with no switch in between. Just the Win PC -- ethernet cable - Opnsense. I don't see any interface errors or collisions in the statistics.

Again the issue repeats every 8 hours, starting at 4am. Trying to understand what is causing this behavior.

General Discussion / DNS weirdness - Unbound DNS

« on: October 31, 2023, 03:13:04 pm »

I am puzzled. A DNS request for servers.rmnoise.com returns IP address 100.64.3.4 while the real IP addresses are 184.80.221.105 AND 174.170.161.132. 192.168.1.1 is my Opnsense FW. Here is a Wireshark capture.



I don't have any DNS issues at all besides the one with servers.rmnoise.com.
Any ideas?

Thanks
