on the videoserver as root run

docker network ls
(new) root@yami:~# docker network ls
a5594cd4c983        grapecall-staging.jitsi        bridge              local

now inspect the docker network with

docker network inspect a5594cd4c983 | less

look for the network of the videobridge grapecall_jvb_1 and note the Gateway IP

docker network inspect a5594cd4c983 | grep Gateway -C3

"Config": [
            {
                "Subnet": "172.24.9.32/27",
                "Gateway": "172.24.9.33"
            }
        ]

now look for the interface that uses this Gateway

(new) root@yami:~# ip a s | grep 172.24.9.33
    inet 172.24.9.33/27 brd 172.24.9.63 scope global br-a5594cd4c983

install iptraf-ng

apt install iptraf-ng

now run iptraf-ng

iptraf-ng

select the correct interface (in this example br-a5594cd4c983)

now you can see the packets as they are running
