I have a IP configured which is not visible for another network (suppose IP: A).
I have a common machine/switch which is in between two networks, now need to set up IP forwarding such a way that the packets coming to IP: A should be forwarded to that machine correctly.
sysctl -a |grep forward
and then set the needed parameters to 1 for
- the interface you want
using sysctl -w parameter
and you will have a router
If the output is 1 IP forwarding is enabled,
If the output is 0, run this command,
cat 1 > /proc/sys/net/ipv4/ip_forward
ipv4 and ipv6 directories are present inside "/proc/sys/net/".

Does anybody know if it makes a difference to enable IP forwarding on the (linux) host? I know both works (enabled or disabled), but is there a good choice regarding the use of virtio_net inside the (linux) guests?
