I am having a weird problem with the portrange specification. My situation is reversed from most configurations in the FAQ as my host is behind the fw, while the backup server sits in front of it. There is no NAT going on.

 

Amanda was compile from the source RPM, I added the following to the SPEC file:

 

        --with-portrange=850,854 \

        --with-tcpportrange=850,854 \

        --with-udpportrange=850,854

 

I put the server and client RPMS on my backup/tape server, and the client RPM on the client.  Both are running Fedora Core 1 if that matters.

 

Amcheck will work, and I can see the traffic (using tcpdump) running mostly on port 850, sometimes on port 851.

 

The problem is when I run amdump, I get a few things going back/forth on the 850-854 range, and then the server tries to connect to the client  some high number port, in this test, 48111. That isn't going to work. J Why does it do this? Only ports 850-854 are allowed, that's why I specified them in the compile.  Suggestions? Tcpdump output from the server shown below. If I open all ports up at the firewall the software works, so I don't think it's a network/server problem, it has to be related to the allowed ports of the firewall.

 

Thanks,

 

Nick
