[HECnet] Off Topic - pfSense on Hyper-V

I could have a go at completely resetting the config. I will have to wait until the weekend to be able to give it a go.

Although this may not help, OPNsense was based on a fork of pfsense. I have had odd connectivity issues before which has resulted in stripping back the config and starting again, and thinking about it one did happen after an update a couple of years ago where the config didn?t seem to update properly. A rebuild of the config sorted it. Mark Sent from my iPhone On 10 Aug 2020, at 09:57, Keith Halewood <Keith.Halewood at pitbulluk.org <mailto:Keith.Halewood at pitbulluk.org> > wrote: ? Is it something to do with the virtual switch setting that permits/prevents multiple Mac addresses from the same virtual adapter?

I realise this is completely off topic, but I think this list has a lot of experienced networking people, so I am hoping someone might have a suggestion. I have pfSense running as my firewall at home, running on Hyper-V. In case you don?t know, it runs on FreeBSD. I have run it for a few years and really want to get it upgraded to the latest. But when I do the upgrade doesn?t work because every packet in the WAN interface seems to get lost, it just cannot send anything to the WAN. The LAN side is fine. I posted on the pfSense forums about this a long time ago. I got some questions about the MTU, but it was fine I was just wondering if you have any thoughts/suggestions/experiences? Thanks Rob
