| ===================================
| openvpn:2000    net
| openvpn:2001    net
| openvpn:2002    net
| ===================================
| All tunnels ran for weeks without any problem whatsoever.
| Now I need to change the IP of the tunnelend of the second tunnel. After

| When I do a 'shorewall clear' then restart OpenVPN let the tunnel come

| tunnel while shorewall started.
| What can I do to find out what is causing this problem?

Look at your log.
