+network bridge does not work
+
+hi there
+
+the network bridge does not seem to work described as here: https://en.wikibooks.org/wiki/QEMU/Networking
+
+When i add that parameters in a 192.168.80.x subnet, my emulated raspbian ARM gets the IP 10.0.2.15.... While all other computers get 192.168.80.x
+
+The command i use is:
+
+
+qemu-system-arm.exe -M versatilepb -cpu arm1176 -hda 2018-09-03_stretch_inkl_phalcon.img -kernel kernel-qemu-4.4.34-jessie -m 192 -append "root=/dev/sda2 panic=1 rootfstype=ext4 rw" -no-reboot -net nic -net user -device e1000,mac=52:54:00:12:34:56 &
+
+
+Does not build up a network bridge to 192.168.80.x...
+
+The host system i use is win10 x64 v1803
+
+Best regards,
+Jan

+qemu-system-arm.exe: warning: nic e1000.0 has no peer
+
+
+10.0.2.15 is neither a ip in our dhcp range nor an apipa address - strange
+
+but google is pingable, so i have internet.
+
+must be nat, right??
+
+Yes, looks like nat - 10.10.2.15 is not pingable from 192.168.80.x but vice versa... 
+
+but wqhat they write here is not nat: "If no network options are specified, QEMU will default to emulating a single Intel e1000 PCI card with a user-mode network stack that bridges to the host's network. The following three command lines are equivalent:"
+
+And i think my params are right?
+
+...  -net nic -net user -device e1000,mac=52:54:00:12:34:56 &
+
+That comment about e1000 is only true for qemu-system-i386. For ARM machines, there are other default NICs. You should also not mix "-net" and "-device", see https://www.qemu.org/2018/05/31/nic-parameter/ for some details. And concerning NAT, yes the "user" backend is using NAT, see https://wiki.qemu.org/Documentation/Networking#User_Networking_.28SLIRP.29 for details about that.
+
+OK thx.
+
+"The -device option can only be used for pluggable NICs. Boards (e.g. embedded boards) which feature an on-board NIC cannot be configured with -device yet, so -net nic,netdev=<id> must be used here instead."
+
+when i only use "-net nic", i get an apipa address
+
+what do i need for netdev id? n1 as described in your links does not work. messsage: "netdev 'n1' not found"
+
+currently, only one nic adapter is enabled on my win10 host: the ethernet controller.
+
+the other 2, 1x internal wlan and 1x usb wlan is disabled..
+
+"That comment about e1000 is only true for qemu-system-i386. For ARM machines, there are other default NICs."
+
+but why im able to ping google with that config??
+
+"-nic tap,model=e1000"
+
+-> "Device 'tap' colud not be found
+
+incompatible with windows, right? so i need a linux machine with ethx??
