Hey
guys,
I have
some doubts about networking on XCP.
When
I create a VM and start it, the Xen server is creating a VIFx.x
So, here
is my doubts.
When I start a VM and the
Xen server creates this interface is it bridged automatically?
Or do I need to forward its traffic through my LAN
connection?
I tried to
forward the traffic from this interface to my eth0 but it seemed not
work.
Here is
the script that I created and executed on Xen server:
# Always accept loopback
traffic
iptables -A
INPUT -i lo -j ACCEPT
# Allow established connections, and those not coming from the
outside
iptables -A INPUT -m state --state ESTABLISHED,RELATED -j
ACCEPT
iptables -A INPUT -m state --state NEW -i !
xenbr0 -j ACCEPT
iptables -A FORWARD -i xenbr0 -o vif5.2 -m state
--state ESTABLISHED,RELATED -j ACCEPT
# Allow outgoing connections from the LAN
side.
iptables -A
FORWARD -i vif5.2 -o xenbr0 -j ACCEPT
# Masquerade.
iptables -t nat -A POSTROUTING -o xenbr0 -j
MASQUERADE
# Enable routing.
