Hi,
My name is Zulkarnain Kamaludin from Kuala Lumpur, Malaysia. I have setup as follows: Users from outside networks need to communicate with inside host. The inside host only open a single TCP port let says port 15000 and only can talk to the TCP port 15000. The problem is the users outside is opening randomly TCP port and I need to translate this random ports to TCP port 15000. Can it be achieve? Thanks in advance.
rgds,

Hi
Let me brief your question there is one server inside you network which is running service with tcp port 15000 , Outside users want to
access this service from there workstation. I hope this is your requirement then configure the static nat your device
If it is firewall you can use this command static ( inside,outside) xxx(outsideip) xxxx(serverip) -the configure the access-rule in the outside interface
all tcp port 15000
if it is router use this ip nat inside source static serverip outside(transating ip)
and
under the inside interface
ip nat inside
under the outside interface
ip nat outside
i hope this your requirement if not please clarify youre requirement
thanks

Hello,
Unfortunately, it does not look like an IOS router can do what you are looking for. You could try a firewall (ASA) with 8.3 code where there is a workaround to acheive this.
Hope this helps.
