Run this

sysctl -w net.bridge.bridge-nf-call-iptables="0"

then try your firewall again

 Subject: [Xen-users] firewall messing xen setup

hi all,

 i'm trying to understand how networking works on xen, but the firewall is 
messing the setup and i don't know why (it shouldn't block connections of the 
virtual interfaces!)..

 i've the following setup: suse 10.2 with 2 network interfaces, the first one 
remains untouched by xen and is used only by the server itself -no problem-. 
the second one runs on another network and is managed by xen. the second 
interface doesn't work when the firewall is activated and server and 
virual-server can't see each other. none of them can connect to any other hosts 
of this second network.

 bridge is up and running:

 # brctl show xenbr1
 bridge name     bridge id               STP enabled     interfaces
 xenbr1          8000.feffffffffff       no              vif0.1

 everything seems to be correct, interfaces are:

 eth0 - network 1 - xen doesn't use it, works well
 eth1 - network 2 - xen manages it, does not work when firewall is enabled
 vif0.1 - eth1 on server
 vif1.0 - eth0 on virtual server

 what's what i'm missing about xen networking? the server firewall should only 
block connections directed to him, but not those of the virtual server, is it 
right? i have tried to put this interface on the internal zone (no port is 
blocked) and doen't work, i've activated forwarding, doesn't work.. only when 
the firewall is stopped everything works fine..
 any help would be appreciated!
