Openvpn connection established but no tun interface created

[ruser]

Hi,

The openvpn log for client shows 'Initialization Sequence Complete', but there is no tun interface seen using 'ifconfig'. Have anyone observed this behaviour ? Under what scenarios can we see this behaviour ?
Please help in this regard.

please post your logs also,

for now you must correct your configs since they mismatch...

server

cipher AES-192-CBC

client

cipher AES-128-CBC

you MUST use the SAME cipher on both ends.
