Just have a question for yall. I'm currently redoing my cluster and trying to set it up as securely as i can. My question is this. Do Linux bridge interfaces talk to/allow traffic between the bridges or are the isolated from each other similar to vlans. Her is my setup. I have three vlans https://mobdro.bio/
VLAN1 192.x.x.x
VLAN2 172.x.x.x
VLAN3 10.x.x.x(not technically a vlan cause this is on a completely separate and air gapped switch)
i have a device on vlan 1 that im using for testing. when i run an ip scanner for the ip range for vlan 2 it is able to see all devices, but since its on a separate vlan and i don't have intervlan routing setup even if i set a static ip i cant actually reach any of the services. Its probably some other device allowing that to happen but i want to rule out proxmox before i start digging into all my different VM's.
Also if you have any other security tips and tricks for me i would appreciate it. Also just thought i should mention the reason im doing things that way is i have one vlan for backups, replication, shared storage. one vlan for service gui/ssh management, and one vlan for any services that i want to be publicly available ie plex minecraft nextcloud etc.
