Hello,
I have a ovs bridge br-ext and a vlan1012 associated to this bridge. I am
trying to create a iptable rule that forwards the incoming packets in the
hypervisor eth0 to a virtual machine with ip address 192.168.9.217. I can do
telnet from the hypervisor to 192.168.9.217 8090. But I can not do telnet from
outside hypervisor even if I have the ip tables rule described below in the
hypervisor. if_oam = eth0 = 10.95.80.20 so I am trying from outside the
hypervisor telnet 10.95.80.20 8090 but it is not working.
Could you help me?
