Just had some problems running OpenVPN in mutiwan mode on ClearOS 5.2 SP1.
Sometime connection got dropped down and user could not reconnect. Problem was solved then i disabled on of the multiwan NICs. What fixed the problem was setting OpenVPN to work in TCP mode instead of UDP. I guess packets were sent using wrong NIC on UDP based connections.
Edit /etc/openvpn/clients.conf
and set "proto tcp"
