Hi,
we have a problem. we have a router which performs NAT, and behind router we have ASA. in inside we have a server. we need requests which come to our outside interface with port number 9000 convert to server ip with port number 443. we do port address translation on router :
ip nat inside source static tcp 192.168.10.10 443 interface GigabitEthernet0/0 9000
and on ASA we permit everything for test.
but our config doesnt work. what should we do?

Hi,
can you provide the config of the ASA.
Regards.
Alain.

Hi,
Can you provide show ip nat translation output from your router as well? Most important to look at is, if the translation is happening. There could be a chance that the traffic is really not coming in with Port 9000 on the router. Hence translation doesnt happen.
