I've not tried running OpenVPN against itself in a test bed. I no longer have the option as I had my provider downgrade my problematic VM from 4.4 to 3.4, which made the problem disappear.
The OpenVPN config's I use are pretty standard. Server: port XXYYZ dev tun ca CA cert CERT key KEY dh DH server A.B.C.D 255.255.255.0 ifconfig-pool-persist ipp.txt keepalive 2 8 comp-lzo user nobody group nobody persist-key persist-tun status openvpn-status.log verb 3 push "dhcp-option DNS 8.8.8.8" push "dhcp-option DNS 8.8.4.4" Client: client dev tun proto udp remote A XXYYZ remote B XXYYZ resolv-retry infinite nobind user nobody group nobody persist-key persist-tun ca CA cert CERT key KEY ns-cert-type server verb 3 ping 2 ping-restart 5 On Sat, Aug 1, 2015 at 12:45 PM, Egoitz Aurrekoetxea <ego...@sarenet.es> wrote: > Could you paste your onpenvpn’s server and client config files?.
