Thread-topic: [Xen-users] firewall messing xen setup

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
                                                        peth1
                                                        vif1.0

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
peth1
vif0.1 - eth1 on server
vif1.0 - eth0 on virtual server
xenbr1
lo

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!

regards

jorge
