cluster logger not receive messages from other nodes

Zeek
1

Hi,
I've been using a simple clustered config. My config:
[logger-1]
type=logger
host=localhost

[manager]
type=manager
host=localhost

[proxy-1]
type=proxy
host=localhost

[worker-1]
type=worker
host=localhost
interface=eno2

This cluster is not capturing any packet and I found it is because the nodes are not communicating with each other. cluster.log:
1629160260.237419 logger-1 created clone store: zeek/known/certs
1629160260.237419 logger-1 created clone store: zeek/known/services
1629160260.237419 logger-1 created clone store: zeek/known/hosts
1629160260.237419 logger-1 listening on :47761/tcp
And it doesn't grow any more. My localhost interface is UP, and when I capture traffic on localhost using tcpdump, I can see SYN packets transmitted to 47761. I'm not sure why logger-1 is not receiving them. Thanks for any help!

Problem solved. Caused by firewall rules.
Here is another problem I'm trying to figure out. When I pin certain cores to listen on one interface, all cores on my machine start to run at full load. Can somebody help with this?
