Re: Port forwarding ASA5506X

ahuertavazquez · ‎06-13-2019

I know it's a very trite subject but I'm already going crazy with this issue

I am configuring a port mapping 53429 --->https, but this does not work.

https

topology: User browser PC port 53429 --->Outside ASA ---> inside ASA ---- Device DVR-app https service

I has configured the following

object network DVR-web
nat (int_video,outside) static interface service tcp https 53429

with the acl

access-list outside_access_in extended permit ip any object DVR-app

but it is not working, any help I will thank you

Sheraz.Salim · ‎06-13-2019

try this
!
object network DVR-TEST
host x.x.x.x
nat (int_video,outside) static interface service tcp 443 53429
!
access-list outside_access_in exten permit tcp any host x.x.x.x eq 443
access-group outside_access_in in interfacec outside
!
packet-tracer input outside tcp 8.8.8.8 12345 1.2.3.4.5 53429

where 1.2.3.4.5 is our ASA outside ip address.

Oops, I omitted a line and that's why I showed the error,
I already applied the suggested lines but the problem continues

hm.. can you try this please.

object service 53429
service tcp source eq 53429

!

object service HTTP

if the above even does not work.share the output command "show nat detail"

please do not forget to rate.

ahuertavazquez · ‎06-17-2019

I am assuming that the values of "DVR-web" and the "wireless-house" interface in the nat are for simulation; because they are not the real values that I have.

taking into account thats, here is the output of the packet-tracert
