Unable to connect to Bridged Win10 VM

im sorry if this is the wrong place to ask but ive been trying for a few days to get my Win10 VM to communicate with my ARch Linux Host Machine so i can ftp Files between for Example
So i set up the bridge correctly(?)
As all i did was this
```
#Creation of bridge interface br0 and activation
ip link add name br0 type bridge
ip link set br0 up

#Activate enp39s0 if needed (you can't bridge a down interface).
ip link set enp39s0 up

#Flushing ip address on enp39s0 (if needed)
ip addr flush dev enp39s0

#Link enp39s0 to br0
ip link set eth0 master br0

#Obtain an IP for br0
dhclient -v br0
```
and while that works as in both have Internet again i still cannot seem to get a FileZilla Connection working
I just keep getting an Error Connection Refused even if i have my Windows 10 VM Firewall down :(
```
Status:    Connecting to 192.168.178.60:21...
Status:    Connection attempt failed with "ECONNREFUSED - Connection refused by server".
```
also heres my ip route output if it matters
```
default via 192.168.178.1 dev br0
default via 192.168.178.1 dev enp39s0 proto dhcp src 192.168.178.77 metric 20100
192.168.122.0/24 dev virbr0 proto kernel scope link src 192.168.122.1 linkdown
192.168.178.0/24 dev br0 proto kernel scope link src 192.168.178.60
192.168.178.0/24 dev enp39s0 proto kernel scope link src 192.168.178.77 metric 100
```

Re: Unable to connect to Bridged Win10 VM

- Is a FTP server running on your Arch host and have you tested it (via another device in your network)?
- Is this a KVM/libvirt virtual machine?
- Why not using the existing vibr0 interface? According to the Wiki it should have "bridge" functionality.
- A separate bridge (br0) with only eth0/enp39s0 as the master device will in itself do nothing useful - what did you expect?

I did not try it yet with Another Device
Yes its a KVM Machine
Ah i actually did not knew that >.> (i know RTFM but when searching the Internet i did not think of going to the arch wiki -.-)
Well i thought if i bridge them together it would work as atleast thats what was working on that Gentoo Users Guide :( (The Steps that i copied from theyre Gentoo Forum Post Here)

I will now try vibro0 and see if that makes it work then :P
