Don’t do
auto eth1
iface eth1 inet static
address 10.1.3.33
netmask 255.255.255.0
gateway 10.1.3.1
dns-nameservers 192.168.2.11 192.168.2.12
Just only
auto eth1
Maybe this helps?

Onderwerp: [libvirt-users] Problem in bridged networking
Hello,
I am facing some problems in bridged networking.
I have successfully created a bridge br0 and added a virtual machine to it. Now the
address of virtual machine is 10.1.3.31. I am able to connect to this virtual machine by
another computer on same network.
The virtual machine is hosting a simple python http server on port 8000, while some other
service is running on port 80
When I try his on my main server :
# curl 10.1.3.31:80<http://10.1.3.31:80>
Response I get is this :
* Rebuilt URL to: 10.1.3.31:80/<http://10.1.3.31:80/>
* Hostname was NOT found in DNS cache
* Trying 10.1.3.31...
* Connected to 10.1.3.31 (10.1.3.31) port 80 (#0)
GET / HTTP/1.1
User-Agent: curl/7.35.0
Host: 10.1.3.31
Accept: */*
* Recv failure: Connection reset by peer
* Closing connection 0
curl: (56) Recv failure: Connection reset by peer
But when I try this on any other port
# curl 10.1.3.31:8000<http://10.1.3.31:8000>
Response I get is this:
* Rebuilt URL to: 10.1.3.31:8000/<http://10.1.3.31:8000/>
* Hostname was NOT found in DNS cache
* Trying 10.1.3.31...
* connect to 10.1.3.31 port 8000 failed: Connection timed out
* Failed to connect to 10.1.3.31 port 8000: Connection timed out
* Closing connection 0
curl: (7) Failed to connect to 10.1.3.31 port 8000: Connection timed out
