My guest network is Bridged on virbr0.
Any hints would be appreciated.

Hey Patrick,
with this post, you opened what I had experienced
before - and it was always a pain to resolve.
At the time, it seemed to have to do with the iptables
firewall rules, and routing permissions.
Unfortunately, I do not recall how I resolved it.
I did wonder if it was a firewall issue, but I haven't changed my
settings recently. Not that that means anything necessarily.

Hi Patrick,
Once you enable ip forwarding:
sudo echo 1 > /proc/sys/net/ipv4/ip_forward
edit the firewall rules to allow in and out from the interfaces
virbr0
and the interfaces comprising virbr0.
For example:
-A INPUT -i wlp2s0b1 -j ACCEPT
.
.
.
-A OUTPUT -i wlp2s0b1 -j ACCEPT
ditto for virbr0
However, you might want to add more restrictions to each rule, such as:
-A INPUT -i wlp2s0b1 -m state --state ESTABLISHED -j ACCEPT
Cheers,
JD
