September 10, 20232 yr Hi everyone, Premise: I have two servers (dell r720) with both unraid installed, same settings, same router model, etc... installed in two different places. On both I have vm but on one, I have problems. in practice I can't open the web page provided by the VM (it works on the other one) The vm in question is homeassistant, but I also tried with others distro but I have the same problem. In the network settings I have already activated bridging and the network on the vm is br0 Strange thing, if on the router (fritzbox 7590ax) I open port 8123 and try to access via the public IP provided by the ISP, it works! I think it's a route problem but I can't figure it out!
September 15, 20232 yr Author Solution I'll answer myself: I had set the network MTU to 1492 on network-settings as an optimization, I left the field blank (default) and magically everything started again!
