Thanks for your reply. My problem, however, is that the NFS servers I'm dealing with run a plethora of OSs. Believe you me, I'd love to run FreeBSD on all of 'em, but that is simply out of my control. The '-h' option for nfsd that was introduced v4.0 would be a great fix for this. What I really need is a means to make the FreeBSD client not be so picky about where the return packets are coming from. I've since learned that this is a long-standing issue with FreeBSD: http://www.freebsd.org/cgi/query-pr.cgi?pr=2858 http://www.freebsd.org/cgi/query-pr.cgi?pr=16239 Thanks, -G /* Glen R. J.

We have this problem both from the :FreeBSD box itself and from the "NAT'ed" clients on the 10.x.x.x networks it :serves. There are two solutions to this problem, both involving fixing the NFS server. The problem is that the FreeBSD NFS server would respond to UDP NFS packets using a different source IP then they were sent to. The solution is to either use TCP NFS mounts, or to use the -h option to nfsd (see 'man nfsd') to force nfsd to bind to and respond to UDP packets using the same interface IP. 'man nfsd' should give you enough information to fix this on your NFS server. You should not have to mess with the clients at all. I'm pretty sure I backported this feature to 3.x. -Matt To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
