Unable to Port Forward on ASA 5512-X ver. 9.1

Eyasu — Fri, 21 Feb 2020 14:32:53 GMT

Hey, guys.

i am kind of new to this forums. And, now, i need your expertise about PORT FORWARDING ASA 5512-X ver.9.1 based on the topology and my detail ASA configuration. All port forwarded worked on Router 2600 series. now, we just remove the Router and replace it with ASA .

My detail topology is below. Further clarification, there is an EPON bridge in between ASA and ISP-Router

Hi,

I think the best way to solve this is to do packet capture on the outside and dmz interfaces.

Here it is an example:

object network obj-10.1.1.16

host 10.1.1.16

nat (inside,outside) static 192.168.100.100 service tcp www www

You will also need to allow the access on acl.

access-list ALLOW-SERVER extended permit tcp any obj-10.1.1.16 eq www

hello andre,

thanks for your support.

the solution you gave me is simply perfect. but, i didn't work for me.

i just cleared out and just only add the way you showed me.

Should I use flow-export command??? and, how can i accomplish that too???

andre.ortega — Mon, 23 Oct 2017 11:18:16 GMT

Flow export is not related with port-forwarding.

Thanks for support guys. But, i still wounder, why CISCO will not allow us to natting and port-forwarding a RANGE of ports for simplicity.

i use this CLI:

network service ALLO_PORT

service tcp source range 2010 2015

and, add that service to the end of access-list

but, doesn't respond. why is that?
