Divne padanie vpn spojenia

V poslednej dobe sa mi zacali mnozit nahodne pady vpn spojenia, zaujimave, ze vzdy len ked mam zapnuty aj VNC a nieco na dialku riesim. Zo strany klienta dojde v nahodnych intervaloch k odpojeniu a naslednemu znovupripojeniu.

atd

Na strane servera vidim len nieco taketo:

Mon Oct 10 14:47:15 2011 read UDPv4 [ECONNREFUSED]: Connection refused (code=111)
Mon Oct 10 14:47:15 2011 MULTI: multi_create_instance called

atd

Nejako sa mi nedari najst suvislost preco to pada, ak mam zapnutu ciste len openvpn tak spojenie drzi, ak mam aj vnc niekedy drzi aj hodinu, inokedy spadne a aj 3x v priebehu 2min.
