Thanks, that means openvswitch doesn't support this situation.
But I think NAT problem will be solved if openvswitch transfers the data via
the connection from private network service to public network service, and it
is just not realized.

Hi,
I have a question about whether OpenvSwitch supports the following requirement:
Firstly, I am sure that OpenvSwitch can connect 2 sub-networks via a tunnel
(e.g. vxlan) -->
Assume the IP address of two hosts are 192.168.1.10 and 192.168.1.147
respectively, what people should do is just to use
"ovs-vsctl add-port br1 vx1 -- set interface vx1 type=vxlan
options:remote_ip=192.168.1.147" and
"ovs-vsctl add-port br1 vx1 -- set interface vx1 type=vxlan
options:remote_ip=192.168.1.10" to link the 2 hosts.
It is clear that this is a DUPLEX task for each host to link to another host.
But it doesn't work on such requirement:
I have a remote cloud machine (named host-1) whose IP is allocated a public
address that anyone can get access to it.
And I have a local machine (named host-2) from a family router whose IP is a
private sub-net, all connections from this host to public service is NATed.
I want to link host-1 and host-2 to create a shared subnet. If I use the
following method,
run "ovs-vsctl add-port br1 vx1 -- set interface vx1 type=vxlan
options:remote_ip=<host-1-ip>" on host-2
run "ovs-vsctl add-port br1 vx1 -- set interface vx1 type=vxlan
options:remote_ip=<host-2-ip (private network)>" on host-1
Obviously, the second command doesn't work.
I want to know whether there is a way to connect host-1 and host-2 to generate
a shared subnet. (Assume I have no access to change settings of the family
router)
Looking forward to your reply.
If you have no access to the family router such that you cannot set
up/configure NAT rules, then I think you will not be able to accomplish what
you're seeking.
