arp request not working in a Layer2 Bridge Connection on Ubu
Posted: Mon May 22, 2017 5:34 pm
Hi,
i have a setup of VPN Server on Windows and a VPN Bridge on Ubuntu. I use this scenario also for other bridge connections that work fine, now this bridge is installed on a provider that runs openstack platform on kvm i have not used before (Prom mode is enabled).
the problem i have is that the Softether Tunnel seems to be up, i see the local ip of the bridge and also see the virtual IP from my L3 switch. but it seems there is no arp resolution possible trough the tunnel.
this is the example output from the bridge:
root@sevpngw:~# ip neigh
10.xx.12.251 dev eth0 FAILED
10.xx.12.1 dev eth0 lladdr fa:xx:xx:6c:da:17 REACHABLE
We have already checked a lot and i don't know where can be the issue. Any idea?
