Public IP on virtual machine network issue

[Marcin Groszek]

I have been struggling with this for weeks and I was unable to find an 
answer on line. Perhaps someone here can help me.

Oracle linux 8 running virtualization:

hardware node has a public IP address on interface bridge0 and physical 
eno1 is a member of the bridge0

a virtual OS has interface bridged to lan and source is bridge0, Ip 
address of virtual OS is also a public from same class as the hardware node.

I can route in and out of virtual, I can ping from hardware node to 
virtual and vice versa, so the routing works as it should, sort of.

When I try tracepath or traceroute from outside to virtual I get !H on 
last hup

same result when I try to do the same form hardware node to virtual I get !H

Also, when I telnet (TCP) to a specific port on virtual where I have a 
daemon LISTENING OR NOT I get: No route to host. Same experiment works 
just fine for ssh port.

Firewalld is not running, and I just have very basic iptables rules like 
allowing external address block to ssh to hardware node and to virtual 
dropping connections from all other sources

This issue presented it self when I attempted to setup a galera node on 
virtual and ports 4567 is responding but 4568 and 4444 are not, but the 
daemons are running and I can clearly see lsoft showing "LISTENING"

I capture the traffic and the tcp as well as udp are getting to the 
virtual. Is there a preconfigured netfiltering that I am not aware of?

What am I missing?
