TAP interface created automatically

[rujoesmith]

I noticed that my router was assigning 2 ip's to proxmox. I can ssh and access the webgui through both of them. It seems like a tap interface was created and is somehow connected to vmbr1. Vmbr1 is my LAN interface hooked to the router. This is a fairly fresh install, I haven't changed much yet and am just trying to learn the basics.

Could anyone explain what tap100i1 is and if/how I should disable it?

Never mind, I had something bridged wrong it seems

the tap interface is the device which map your guest vm virtual nic to the real work.

for each vm nic, you have a tap interface (tap<vmid>i<netnum>).

Then, the tag interface is plugged in vmbrX.

Is there a way to give the tap device a fixed static MAC address?

the mac of the tap is not the mac used by the vm. (the vm use the mac of the qemu device)

So they are really no reasy to fix a static mac for it.

I see my web GUI. I am trying to get across that ssh and http(s) are working from this node but ping and network access fail. My router doesn't even show that this node is connected to it in anyway? I don't even see how this is possible? I have turned off firewall and still have same issue?
