Evening!
I ditched firewalld and swapped to configuring iptables manually…
I’ve also made some basic calls with media going in/out of the same
interface and I’m still seeing the audio stop completely or become
one-way once kernelized.
On the two different interfaces, I get no-way audio once kernelized.
Weird!
Could this be related to the kernel module being unsigned (running
CentOS 8 Stream)?
kernel: xt_RTPENGINE: loading out-of-tree module taints kernel.
kernel: xt_RTPENGINE: module verification failed: signature and/or
required key missing - tainting kernel
kernel: Registering xt_RTPENGINE module - version git-HEAD-5bf2c50a

No, that is expected and perfectly fine.
Have been pulling my hair out!
[root@blahblah zgadmin]# iptables -L

That looks fine. How about the actual network setup? Any network
namespaces, policy routing, or other unusual setup in place?
Cheers
