OPVN UDP Client DPD?

[c-mu]

Hi,
I'm wondering if there is a dead peer detection config flag if you are using UDP VPN Client connections.

At server side, I set "keepalive 5 10". The server detects a client loss after round about 20 seconds. At the client side, it seems that it does not have any impact.

My Client needs up to 60 seconds, until it recognize, that the connection was interrupted. I could change to TCP, and the client's will instantly notice about a connection loss, but on cost of bandwidth.

Thank you!
