Have you tried with the FW stopped?
Well I stopped firewalld, though I don't think that actually stops the FW itself, i.e. iptables in the kernel.
Makes no difference.
Well, good news and bad news. The good news is that I think I've been able to reproduce the problem. The bad news is that it is late in my day and I've had a bit of a "night cap".
But, do this, with the firewall stopped reboot the guest. Then see if it works. When I reproduced the problem it was necessary to reboot the guest to get it working.
I did that, and sure enough the guest came back up with net access. Pings worked both ways.
Then after a minute or two it went down again, without me touching the FW. This is consistent (if consistent is the word I want) with what it's been doing for the past couple of days.
I'll do more in my AM.
Thanks again.
