Should I handle TTL (Time To Live) status after pe (wodVPN)

David,

Usually no. However, you can try setting Timeout property in order to set how long you wish connection to be kept alive in case there is no communication between peers.

You can find more info on Timeout property here: http://www.weonlydo.com/VPN/Help/wodVPN-Timeout.html

Hope this helps.
