Nope. Redirection and port forwarding won't work...but... I played
around with the autofw module of the ipmasqadm tool and found this:
"-d <type> <low> <high> specifies a set of ports which will
not use the default high range
(60000+)masquerade port area"
YES! Exactly what I needed (I hoped). So, I took a gamble and
entered this into the gateway machine:
# ipmasqadm autofw -d udp 10080 10080
Then on the tape server:
# amcheck -c DailySet1
The answer:
Client check: 5 hosts checked in 2.136 seconds, 0 problems
found.
YES!!! It worked! After two full days, I've finally got it working!
And such a simple solution. I could change the high to include the
kamanda port, but why? :) *sigh* Anyway, kudos to Juanjo and the
Linux ipmasquerade team! You saved me the headache of installing a
kerberos server (the comments in dgram.c in amanda's source code noted
that the program doesn't care what port it goes over if kerberos is
enabled).
It's now time for a beer!
Later!
