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
