19.7 Legacy Series / Dynamic DNS won't update

« on: January 15, 2020, 01:18:41 am »

Using Cloudflare as DDNS intermediary.  Despite repeated reboots and restarts in the dashboard, the cached IP address will not update (currently the old IP in red).

Is there a script I can install into Cron which will solve this problem?  Or is there another way to make it work?

18.7 Legacy Series / Traffic Shaping with FQ_Codel

« on: January 18, 2019, 05:40:20 pm »

I've been struggling with this issue for some time, and though I seem to have FQ_Codel working with normal network business traffic, video streaming, etc., it doesn't seem to work correctly with VOIP.  Probably a config issue on my end, and I need some insights as to what to do.

Voice quality using G711-u (US protocol), is choppy and crackling, both inbound and outbound calls, not for LAN only calls, just to WAN/external calls.

Some background:
Running latest opnsense on a stand alone "appliance".  Works great!
Use 3cx vOIP phone system (debian) on its own virtualized instance within Windows 10 Hyper-V.
3CX has its own firewall checker to make sure ports and NAT is configured correctly, and all these checks pass.
Updated the Intel i210-T1 NIC on the server running the 3cx instance to latest drivers and tweaked settings for best performance.

I've configured pipes, queues, and rules as shown in the three screen shots. This was based on the article posted here:

https://www.lullabot.com/articles/eliminating-robots-and-voip-glitches-with-active-queue-management

At network quiet time last night, I blocked all traffic except to my testing browser on ubuntu and I ran a dozen network checks at dslreports/speedtest to get an average download / upload speed.  That's how I came up with the up and down pipe speed.

So, I'm wondering, should there be dedicated pipes / queues / rules just for VOIP?  How would they be set up?  Using only max 4 simultaneous calls as a reference (small system).

Thanks for your help.

18.7 Legacy Series / SpeedTests Not Working Right - Firewall Rules?

« on: September 28, 2018, 02:55:13 am »

New installation, can surf internet and download files OK.  I have Cable 100 down / 10 up connection.  I'm concerned that I don't have correct rules in place to facilitate accurate speedtests.  Google Speed test craps out (attachment a), DSL reports throws an error consistently on upload (attachment-b).  I've tried a new nic on my machine, as well as turning off Bitdefender AV, with no change in results.

I've attached current firewall WAN and LAN rules.
