But the reply packet never got acknowledged by the server.
Somehow it got lost or corrupted.
Default route for reverse path not correct?  Wrong subnetmask?
Try do get a network trace at the client and server, and inbetween
(don't know how to accomplish that on a PIX firewall):

Solaris:
    snoop -x42 host x.x.x.x proto udp port 10080
using open source (linux and others):
    tcpdump -X host x.x.x.x and udp and port 10080
Or other programs that have the same capabilities (ethereal etc).

Before guessing how to fix it, we must know where the problem is.
Is the packet lost?  or is it broken?

Quick recap: Server grolsch tries to back up client dominion. It worksfor the partitions of /, /usr and /var. As soon as I tell grolsh to backup dominions /u00 partition (a 45G partition, but presently only 177Mfull w/approx 2000 files) it will fail. I have since removed /u00 frombackups to at least keep things working in the meantime but I would likethat data backed up :-)

I have moved the amanda server to public IP space. It is still behind aPIX firewall, I just got rid of the private IP to public IP mappings.This didnt fix it :-) Not that I thought it would, I just got annoyed atsome of the routing.

I ran tcpdump on client and server, the dumps are on the following page,lined up as best I could to show the flow. It seems when doing thepartition that makes it fail, a bunch of packets do not get from theclient to the server. Since I am no expert in TCPdump or interpretingits results, I hope this helps figure out the problem.
