Hi All,
I'm using one of my Fedora machines as a router between 2 networks. The two
network devices on the machine are called enp0s25 and tun0. On F33 it worked
as expected. However, after an upgrade to F34 It looks like it does not work
anymore.
I tried to give the commands
firewall-cmd [--permanent] --direct --add-rule ipv4 filter FORWARD 0 -o
enp0s25 -i tun0 -j ACCEPT
firewall-cmd [--permanent] --direct --add-rule ipv4 filter FORWARD 0 -i
enp0s25 -o tun0 -j ACCEPT
But had no success (not even after restarting firewalld).
Try tcpdump on both interfaces to see what is appearing there.
Then you could have a look at the counters for the related iptables rules to
understand if they are being triggered.
(assuming iptables is involved, not sure if firewalld has been switched to
nftables backend)
Regards.
