RHEL 8 cockpit routing mess
on a perfectly routing system. I created a bridge using cockpit - added eno2 and it worked fine. ping from other host on network etc.
but then i deleted it and fter that only eno1 is pingable and tcpdump shows ping packets are reaching on other NICs like eno2 but, there is no route back to source.
i do not see any difference in the routing table. I am suspecting something is messed up inside cockpit or networkmanager configurations for routing.
ping to .146 still works - fails for all other intfcs!!!
routing:
