Subject Re: [DEVCLOUD2] Internet access on VMs

Ended up solving this with IP forwarding and iptables.

Modified the devcloud.cfg to use 192.168.56.10 as the gateway.

Enabled IPv4 Forwarding:
sed -i -e 's/#net.ipv4.ip_forward=1/net.ipv4.ip_forward=1/g'
/etc/sysctl.conf

Setup appropriate iptables:
-A FORWARD -i eth0 -o xenbr0 -m state --state NEW,RELATED,ESTABLISHED -j
ACCEPT
-A FORWARD -i xenbr0 -o eth0 -j ACCEPT

-A POSTROUTING -o eth0 -j MASQUERADE
