the issue has been fixed by restarting the hyperV - VM machine!

I'm facing a strange issue after updating to the new patch. Whenever I visit the firmware section, the system restarts. Is this a known glitch, and how can I resolve it?

thank you all, i guess this is something to be consider for the next update adopting STARTTLS in Monit

I guess, "Mail Server SSL Connection" doesn't do STARTTLS, it rather just let Monit connect via SSL (usually port 465).
So maybe Monit connects successfully if you remove this check.

Or you can try port 465. Don't know, if Office 365 supports this.

i have tried that it did not work! im not sure if Monit is design to support such connection, although gmail adopt the same yet it can be connected that what i have seen in youtube!

Mine works with SSL Version set to AUTO

are you using MS email domain? if so could you please share the setting

Hello everyone,

I'm trying to set up a reporting system using Monit, with email alerts forwarded through my Hotmail account. However, the setup isn't working, and I'm receiving the following error:

SMTP: Mailserver response error -- 451 5.7.3 STARTTLS is required to send mail [DX0P273CA0003.AREP273.PROD.OUTLOOK.COM 2026-04-21T17:04:23.671Z 08DE9DD04CF197D8]

STARTTLS is mandatory for authentication, but it seems Monit isn't initiating a TLS connection properly. Has anyone successfully configured Monit to send emails via Hotmail/Outlook.com? If so, could you share the correct SMTP settings or any workarounds?

the opnsense is a B-router

Yes, I'm running opnsense in Hyper-V, the LAN NIC is 2 GBs aggregated in windows server
I'm using two dlink DUB-1312 aggregated. in Untangle was working fine for the last 4 years it was showing 2 GBs NIC but in opnesne the lan and wan showing 10 GBs, I'm not sure if this is a driver related issue? or it is not designed to recognize 802.3ad protocol?     

Why I'm getting this message?

   [100716] <Error> -- bridge0^: error reading netmap data via polling: No buffer space available

how to solve it!!!

for those who face the same issue, i have managed to fix it.

at first you required to enable Promiscuous mode and then select all interfaces that you would like to monitor in Listening interfaces, select the bridge interface in the WAN interfaces option (NetFlow).

everything will work fine.

i have setup opnsense in hyper V acting as Transparent Filtering Bridge "B-Router".
everything is working fine, when enabling netflow i loss network connection, everything goes down, there is no traffic downstream of the opnsense.

i have to disable the option and restart the opnsense again. how i can solve this issue, i need to export netflow to external app!

i have fixed the issue, you require to enable router advertisement guard in Hyper-V 

Currently I'm using Untangle NGFW and deployed in Hyper-V
the LAN interface is set to source and the WAN is set to destination and in the firewall the LAN is set to bridge. for the last 4 years the setup served me well

in OpnSense i have used the same settings in Hyper V and followed the instruction mentioned in here (https://docs.opnsense.org/manual/how-tos/transparent_bridge.html) but i can't ping the upstream router there is no internet, i have all options in the virtual switch of hyper V (Source, destination and non).

the mac address for the LAN and WAN are correct between the Hyper-V and Opnsense

How to setup Opnsense as a secondary firewall.
im moving away from Untagle and i want to use the same setup.
