Hi All,


I am running ubuntu-trusty arm64 server image as dom0. I have enabled CO= NFIG_BRIDGE, CONFIG_IPV6, CONFIG_NETFILTER in linux 3.18. Xen version is 4.= 5 rc1. 


in Dom0 post boot did the following


a) brctl addbr xenbr0; 

b) brctl addif xenbr0 eth0

c) Updated /etc/sysctl.conf 

net.bridge.bri=
dge-nf-call-ip6tables =3D 0=0A=
net.bridge.bridge-nf-call-iptables =3D 0=0A=
net.bridge.bridge-nf-call-arptables =3D 0

d)

iptables -I FO=
RWARD -m physdev --physdev-is-bridged -j ACCEPT


e) sysctl -p /etc/sysctl.conf
f) /etc/init.d/networking restart
g) dhclient xenbr0

xenbr0 gets an IP. 

h)vif =3D [ 'bridge=3Dxenbr0' ]. Star= ted domU
g) domU got an ip.

Now the problem is domU is able to ping dom0 but not any other host. W= hile dom0 is able to ping any host.


There could be something missing in my steps, can you please help 

-Regards
manish
