amanda: DNAT issue

Hi guys,

Actually I was successfully configured amada and it can backup and recovery. I used direct connect from my SAN server to modem.

Now I am having problem when I tried to connect SAN server to proxy server first. The modem is connected at proxy server. So any packets coming will go through to modem first and then proxy server. I used port range 50000-50100 tcp for amdump and port 10080 for amcheck. I already did DNAT in modem. Just add "50000 50100 tcp" at modem.

I am using shorewall in my proxy server. Here is my DNAT on shorewall:-
DNAT net loc: tcp - 50000:50100

but I did not DNAT udp port in my shorewall becoz udp did not make any issue.

Here is shorewall rules in client side(client is located in US):-
ACCEPT net:x.x.x.x $FW udp 10080
ACCEPT net:x.x.x.x $FW tcp - 50000:51000
where x.x.x.x is my public ip in Malaysia. So, backup from US to M'sia.

I can amcheck but cannot amdump. Anyone who are expert about DNAT? Please advice.
FYI, my SAN server doesnt have firewall
