Cross-container/vm communication security on Proxmox
Cross-container/vm communication security on Proxmox
Hey, I've got a bunch of services all running in their own containers/vms on Proxmox. All of these have their own ips that are accessible from my network.
I also have a container with a reverse proxy, which acts as a gateway for access to these services (it's IP is the only one allowed to go through the firewall of each service).
These services have http servers, no encryption. Could someone on my network listen to comms between a service and my reverse proxy?
Would have to play around with VLANs if that's the case...
Thanks

Unless someone has physical access to the ports/switch that the traffic flows through, they would not be able to see anything besides broadcast/multicast traffic if they were just snooping with Wireshark. The internal switch of proxmox and any hardware switch you have will forward unicast traffic to the ports those Mac's reside on, so without port mirrors setup, no one but you should be able to see that traffic.
Good to hear, thanks!
