VERY VERY strange behavior of 18.1

[roli8200]

Hello

Its about a opnsense 18.1 on a vmware esxi 6.5.

During tests we have noticed that some IP packets are fragmented by 1434 bytes.
To test the maximum MTU the underlying interface can deliver, I exceuted the command:
ifconfig em0 hwfeatures


This causes the interface to crash somehow and come suddenly up again, always with the fixed ip address of: 195.49.42.34
ALWAYS. Tested it three times, with reboots between.
The interface had the originally configured ip of: 10.1.110.251/24
There is absolutely no DHCP Server is in the that network nor on the firewall.

We have no (absolutely no)  relationship in any form to this IP address or the network that belongs to it,
nor with the owner of the network.

I have already experienced many strange, weird and disturbing things with pfsense and opnsense.
Things that contradict any common sense.
This, however, surpasses it by far.




Based on whois, this ip belongs to:

Would you mind trying at least 18.1.x. Meanwhile 18.7.x and 19.1.x have been out for a while.
