Your mails really help :-) I've read many notes about that problem and that the firewall must be opened etc., but none stated how to fix those ports! > It could be any number of things, but probably harmless and properly > ignored for NFSv4.

The server and clients in charge are still running SLES 10 SP2, and it doesn't have the rpcdebug command. However, SLES 11 has it, so I will check when all the servers and clients have been upgraded.
