[Xen-users] routed networking: ping yes, tcp-connection no

[Julian Hagenauer <chaosbringer@xxxxxx>]

Hi,
routed networking does not work for me now.
i can ping the vm and from within the vm, but i can not do any connections.

forwarding is 1.
dom0 is julian.chaosbringer.de is 192.168.1.3.
domU is vm01.chaosbringer.de is 192.168.1.2.
I have no firewall etc running.
Xenversion is 3.0.2.2

I invoked domU with 
'xm create -c /dev/null kernel=/boot/vmlinuz-2.6.16-xenU name=small 
memory=96 disk=file:/home/julian/vserver/images/wscore.img,hda1,w 
root=/dev/hda1 ip=192.168.1.3 vif="ip=192.168.1.3"'
This is what tcpdump says:
13:01:02.865864 arp who-has julian.chaosbringer.de tell vm01.chaosbringer.de
13:01:02.865916 arp reply julian.chaosbringer.de is-at fe:ff:ff:ff:ff:ff

What does that mean? julian.chaosbringer.de tries to get a 'syn' from 
vm01, but gets not reply?
routingtable of dom0:
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use 
Iface
vm01.chaosbring *               255.255.255.255 UH    0      0        0 
vif2.0
192.168.1.0     *               255.255.255.0   U     0      0        0 eth0
default         .               0.0.0.0         UG    0      0        0 eth0

routingtable of domU:
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use 
Iface
192.168.1.0     *               255.255.255.0   U     0      0        0 eth0

xend-config.sxp looks like ( i removed the comments ):
(xend-relocation-server yes)
(xend-relocation-hosts-allow '^localhost$')
(network-script network-route)
(vif-script     vif-route)
(dom0-min-mem 196)
(dom0-cpus 0)

Thanks,
Julian
